Why Do Men Fall Asleep After Sex? More Questions You'd Only Ask a Doctor After Your Third Whiskey Sour

Rate this book
The Doctor Is In . . . Again!

Did the mega-bestselling Why Do Men Have Nipples? exhaust your curiosity about stuff odd, icky, kinky, noxious, libidinous, or just plain embarrassing? No, you say? Well, good, because the doctor and his able-bodied buddy are in! Again! Mark Leyner and Billy Goldberg, M.D., now take on the differences between the sexes—those burning questions like Why doesn’t my husband ever listen? or Why does my wife ALWAYS have to pee? And of course, Why do men fall asleep after sex?, plus plenty of others to keep you fully informed.

Full of smart and funny answers to an onslaught of new questions, all in a do-ask-we’ll-tell spirit that entertain and teaches you something at the same time, Why Do Men Fall Asleep After Sex? offers the real lowdown on everything everyone wants to know about all things anatomical, medical, sexual, nutritional, animal, and mineral, but would only ask a physician after a few too many, like:

• Why do you have a “bionic” sense of smell when you’re pregnant?

• Does peeing in the shower cure athlete’s foot?

• Is a dog’s mouth clean?

• Can you breastfeed with fake boobs?

• Does thumb sucking cause buckteeth?

• Do your eyebrows grow back if shaved?

Bigger, funnier, and better than ever, Why Do Men Fall Asleep After Sex? proves that in the battle of the sexes, as in most things, a little Q&A is a safe, effective, minimally invasive remedy.

Mark Leyner

28 books337 followers
Mark Leyner is an American postmodernist author known for his surreal, high-energy prose, absurd humor, and densely layered narratives. A graduate of Brandeis University and the University of Colorado, Leyner studied under postmodernist Steve Katz and launched his literary career with the short story collection I Smell Esther Williams (1983). He gained a cult following with My Cousin, My Gastroenterologist (1990) and Et Tu, Babe (1992), and continued to experiment with metafiction in novels like The Tetherballs of Bougainville and The Sugar Frosted Nutsack. His writing is characterized by sprawling imagery, extravagant vocabulary, and a wild mix of pop culture, medicine, and satire. Leyner’s nonfiction collaborations with Dr. Billy Goldberg, including Why Do Men Have Nipples?, became bestsellers that blended comedy and real medical facts. He has also worked as a columnist for Esquire and George, written for MTV’s Liquid Television, and co-authored the screenplay for War, Inc.. A lifelong innovator, Leyner has remained a singular voice in American fiction. His more recent books include Gone with the Mind, Last Orgy of the Divine Hermit, and the 2024 retrospective A Shimmering, Serrated Monster!: The Mark Leyner Reader. He lives in New Jersey and continues to influence readers and writers with his singular, genre-defying style.

"Why Do Men Fall Asleep After Sex?: More Questions You'd Only Ask a Doctor After Your Third Whiskey Sour" is the second book by Mark Leyner and Dr Billy Goldberg. It's just as funny as the first one and the cover question is certainly one that we've probably all wondered about even if we never actually put it into words. There is, naturally, a medical answer to this question, but I won't give it away. Suffice to say that it's not ALL their fault! Here's a few more, er...interesting questions: "What is that sound a vagina makes after sex?" "Does that black stuff athletes wear under their eyes really stop sun glare?" and one of my favorites "Why don't men listen"...the last one, I'm convinced, IS all their fault!

Another book chock full of humor and knowledge, and yes, I did let my teenagers read this one too.

Meh. It was a fun idea but poorly executed. It wasn't funny even though they tried really hard. They also breezed through the interesting science way too fast. Fail.

Very entertaining read. This is to you Mr. Leyner and Dr. Gberg.

Initially, the IM parts seem awkward and out of place, but after you read more of it and get to know the two people, it becomes a good filler for the questions and their answers. I used to read only 4 pages a day, while eating or so on. It's a good dose of everyday laughter and useless medical knowledge

The follow up to the highly successful, and humorous, Why Do Men Have Nipples?. Leyner and his medical colleague, Dr. Goldberg research and answers more medical trivial questions that everyone is thinking about when you're drunk. In these passages, the duo work to not only answer, but inform & debunk certain assumptions the general public seems to hold in their minds.

Why Do Men Fall Asleep After Sex? follows the same formula as the first book. As we begin with passages that inform us about what category the selected topics fall into, then go into the Q & A with either Leyner or Goldberg answering, then ends each chapter with an online transcript between the two as they discuss in their chats about the creation of the book. I felt the topics were much more broader than the first one as things are covered more in depth here than before. One difference is that the introductory passages are from Dr. Goldberg's view as Leyner joins him in his sessions. It's pretty crazy when you read into how two polar opposite personalities work together. However, I found the online chat to be more of dud than grabbing here. Regardless, this book is still quite funny and very informative on caring for yourself and bringing awareness on less discussed questions that you shouldn't be afraid to bring up with your doctor.

Does not really make sense to read this now that we have incredible search engines. But who actually asks most of the questions that are in this book?

The dialogue between the two co-authors might be amusing for some, but I found it distracting. I guess it's a change of pace to mark a change of chapters.

By the author of "the sugar frosted nutsack", this is the sequel to the remarkable "why do men have nipples?"m which answers some of life's most important philosophical questions, this totally serious volume will provide answers to all the seekers of the deepest truths for generations to come.

Like their previous book, the questions answered are fun and informative but everything surrounding them is mind numbingly tedious that I skipped it all. Filler for the sake of filler. It's a shame, the book would actually be better if they just removed it all.

A nice book to read a little bit of at a time. The IM transcripts are hit-or-miss, comedy-wise.

What a stupid book. Penis and erection jokes galore. Spelling (eg “dissapoint”) and punctuation errors galore.

I would have enjoyed more if random instant messenger transcripts were cut out. This is a humor filled Q/A all about weird body issues.

In the true punk spirit of "contempt for the audience". I asked for people's book recommendations, and ignored them all.

There was a book on the Bestseller list recently called "Why Do Men Have Nipples?"

I saw this and wanted to check it out, of course. Books like this (to me) are instant bestsellers. Any kind of quirky information sells, it's why snopes.com and The Straight Dope websites are so popular and I think why John Stossel's last book sold so many copies.

Stossel, the poor man's Geraldo and the receipent of "Dr D" David Schultz's real-life piledriver has parlayed his job as 20/20 consumer affairs correspondent into a career as kooky loud-mouth conservative, and frequent Fox News guest. His Myths, lies and Downright Stupidity included his look at various myths and misconceptions.

Of course, Stossel is a bore, and so I imagine the book is no fun at all.

Q: Is bottled water better than tap?

A: Well, because of policies enacted under President Clinton....

Or at least, I imagine it goes something like that. So, you have to always check these books to see who writes them.

I had seen the book a few times before I even realized Mark Leyner was one of the co-writers. I had to check and re-check that it was the Mark Leyner, and it indeed was.

So, I was sold. I didn't pick up "...Nipples?", but I did pick up the follow-up "Why Do Men Fall Asleep After Sex?"

I want to say if books like that interest you, you have to check it out. Leyner is hilarious. I also highly recommend his fiction (which came from a recommendation from defrog years ago, and you thought I didn't listen) to anyone and everyone here.

Read all of his novels (he doesn't have that many). Start with The Tetherballs of Bougainville, if I must recommend one book.

If you like Vonnegut, Sedaris, Hunter Thompson, or Dave Barry, he's not like them, but he's in the ballpark. One of the descriptions I have heard is "Burroughs meets Beavis & Butthead", and as much as I wouldn't wish that label on anyone, it could be close.

If you have read the novels, you will enjoy the nonfiction stuff as well, as the humor definitely seeps through.

Answer: Orgasms cause certain hormones to be released that, coupled with post-coitol exhaustion, generate drowsiness. Why men and not women? No, not just because they are more exhausted! But, also because it appears that some guys sometimes have sex with girls without causing them to cum, therefore not causing the drowsiness. Poor girls, victims of their own poor taste.

Anyway, the book was actually pretty well full of interesting tidbits. Some bits were a little mundane, and then there's the section on pregnancy, but even that was interesting because what this book boils down to is a snopes.com or urbanlegend.com of medical phenomenon. Questions of "Why...?" and "Is it true that...?" left me feeling enriched and enlightened medically and socially while reading this book.

Also, the authors (an M.D. and a zany professional writer) are fun. And, they use a literary technique that I have never seen before, but that actually worked quite well for them: they transcripted their own Instant Messanger conversations that they were having while writing the book. Though I'm sure they thought this would be a chic, cool, ultra modern gimmick, it also turns out to be a fascinating insight into their writing and research processes.

How I Heard About It: I've randomly seen its predecessor, "Why Do Men Have Nipples?" and was slightly interested. It wasn't until I receieved this book as a gift that I really got into it.
How I Procured It: My friend Richard gave it to me for my birthday, and promptly embarrassed me in front of all my dinner guests.
Type: Humor/Facty sort of book/Medical Reference?
Ratings: Story/Content: 4/5 Writing: 3/5
Who would I recommend it to? Anyone who's ever asked those weird health questions, like "Will a watermelon seed really grow in your stomach?" and "What is the hangy-ball thing in the back of your throat for?"
Did it remind me of anything? The IM sections reminded me of some of the conversations I've had with friends, although we're not as witty as they are.
Would I read it again? Sure, it's an entertaining, brain-numbing book. I love it.
Comments: Some of the IM passages get a little hard to follow, but the introductions about their so-called mental health "practice" are hularious. Like I said, this isn't a hard book to read. It's a beach-read. Even the scientific, medical parts are easy to get through, and funny at that.

"Why Do Men Have Nipples?" was fantastic. Interesting questions and a clever "instant messing" conversation format. Very cleverly done, combining intelligent answers to questions we've all wondered, with witty dialogue between the writers. "Why Do Men Fall Asleep After Sex?" is not quite as enjoyable as it's predecessor. The questions and answers are all very interesting, but the format that was so fresh in the first book, began to wear thin by the second. The short stories that began each chapter felt like they were forcing the writers' humor and "look at us, we're so bizarre and funny." antics. Still it was a good read, and some of the facts I learned while reading it, have become great conversation starters.

It is a fun book with useless facts based on questions they got from readers. The facts are actually quite well described and scientifically true. The most bizarre questions are answered in the book and the answers are fun to read. However, they also put in some personal communication between the two authors... I think this is really unnecessary and actually I found it quite annoying... I still need to read the other book (why do men have nipples) I hope it will be as much fun as this book. I will skip the personal communication again.

I would recommend this book as a fun book in between, or on vacation. When you want to read, but don't want to pay too much attention. Or even before a family gathering so you can awe them with your new knowledge ;).

Because they have to do all the work. :o) More of less that's why. I actually liked this book better than the first. It had more variety of questions in it. And I skipped all the boring author conversations so that helped speed things along. While reading I was thinking of how I could make this a fun, witty entry, and now that I'm on here and half asleep again, because I broke my rule about reading these books in the a.m. hours, I can't think of anything fun to stick in here. Oh well. Maybe next time. These really would be handy books to have around the house in case you did have a question about something, then you could just look it up.

In the internet age there really isn't much of a reason for this book to exist because you can easily get online & search for the answers for embarrassing questions you don't want to actually ask out loud. I do it all the time :-) However, for sporadic (ok, bathroom reading in all honesty) reading it's kind of neat to have all sorts of wonky questions altogether like this. I didn't bother too much with the IM sections, they seemed pointless, made-up and dumb however I did like the introductions to chapters, some of them were pretty funny.
I was expecting altogether humour though, and that is not what was delivered in the body of the answers for the most part.

This is what I call a prime example of a "Bathroom Read". Gross as it sounds, this book's purpose to ask all those random questions people have like:

Is it true that you cannot die in a dream?
Can you get herpes from a hot tub?
Why do your ears pop on an airplane?

The answers are funny, informative and interesting. This sequel to "Why do Men have Nipples?" continues to provide us with more answers to life's most pressing questions. In the end it's the perfect book to pick up whenever you have a moment to yourself. Enjoy!

Two guys got together and compiled all those embarrassing questions people ask doctors when they’ve had a few (the questioners not the doctors). The queries are thought provoking and the answers go into all the excruciating detail you could ever wish. At some points you might think, “Whoa! Too much information!” but for anyone who wants to know why this happens or why something is that color or where that smell comes from, this is an amusing, insightful book and a wonderful conversation piece at parties.
