This educational yuri about sex is still fun and informative. I personally learned about fingering safety, elective phimosis surgery, menstrual cup insertion techniques, clitoral morning wood, and the term tribbing. There are also good chapters about femininity and consent. But the best chapter sets the sex ed aside for a bit to give us the meet-cute for Hikari Moriya and her girlfriend Sumire Aikawa.

There is a meta joke about running out of material, but I'll be sticking with this series until they do.

Tsuji-sensei has not quite run through her topic list for teaching her health class, thankfully. From stereotypes to consent to dental dam after dental dam, it’s a cornucopia of coitus. Come for the author who can’t draw boys, stay for the asexual girl who likes cat anus!

This volume is not as funny as the first volume. Who cares? This is the best work on sex I’ve read in ages and it’s at the point where it could be used as a course text (or at least a supplement). It’s better than anything I had in school (we did have cars, I should point out).

With a lot of boxes ticked last time we move into loftier heights such as hymens and menstruation, while dealing with the pressures of society and the importance of consent. Every bit of this is done so well and the back of the book includes links to a sex educator on YouTube and a full set of references.

It’s all wonderful, basically. The menstruation section is absolutely stuffed with details and even covers a wide variety of sanitary product (I never thought I would get to say this anywhere, but I have seen full menstrual cups and I kind of agree with Tsuji’s take). The book is heavily focused on females, but nothing wrong with that, they’re kind of complicated.

The section where the two people least likely to try and attract men are harassed by a male teacher is amazing, leading into a note perfect discussion about standards of dress and the crap that females frequently have to deal with in terms of clothing. It’s also got a great gyaru joke.

Even better is the section on consent, which, like every topic here, dives super deep and discusses a ton of sub-topics. They even take on BDSM (sub topic indeed) and sexual assault role-playing in a super non-judgemental manner. It’s utterly refreshing to see something this up front and, yes, accepting.

Then we have a bonus chapter that turns fan service totally on its head by featuring Tsuji and the co-worker she has a crush on. This ends up being a treatise on being hit on and the hideous nature of pick-up artists. In addition to being something I think young women need to be aware of to guard against, it goes so far as to have Tsuji apologize for all the times she’s asked her object of affection out for drinks.

I still want to see those two get together, they are a great pair, but there’s definitely an acknowledgment that it takes two people to make a relationship and you can’t force and browbeat the situation into happening.

Look, I can only say this and if you have followed my writing a bit you’ll know what a compliment this is - there is an utterly delightful relationship brag section featuring the two lesbian girls and it is not a patch on the other things in this book.

There is nothing wrong with this book - it even discusses some problems with the term fujoshi that I had never even considered before. I mean, it does take the stance that guys never get judged for reading yuri, to which I can only say, maybe where you’re from, dear author.

5 stars. This is an all-timer and every teenager doing sex ed should read this and more than a few adults could benefit from it as well. It’s educational and entertaining both and a fantastic presentation of some very heavy topics. Sadly I can’t give it an extra star for the full 120% it deserves.

Woah I didn't expect it to be THIS good! It's really educating, talking explizitly about genitalia, gender roles, tools and product, debunking myths and criticising systematic and social discrimination. At the same time it maintains a light hearted tone, is funny and tells sweet little stories.
Love the bit about consent and pick up artists in particular.

This manga continues to tackle topics head-on that most sex ed classes avoid or omit through characters who feel like real people and help the material come alive, and I am here for it! Yes, the characters are “types,” but it gives them a clear point of view that makes possible questions and discussions that illuminate things I wouldn’t necessarily think about as an American straight cisgender white male. It also makes it clear how poorly we serve girls in regards to education about sex, and I am really looking forward to volume 3!

The worst part about this series is that fact that it’s sold in plastic wrap and marked as “Mature,” effectively alienating the younger audience that would benefit from it most.

That being said, another really great volume!

This series (and this book) is 120% more informative than any sex ed class I had in school. Not only does it pay attention to the LGBTQIA+ community (there's even an ace character), it works hard to destigmatize the discussion of not just sex, but regular old bodily functions, like periods. Throw in a chapter about male genital cosmetic surgery (apparently advertised heavily in Japan) and the unfortunate associations with the word "femininity," and you have a winner of a book that doesn't just shoot for acceptance and education - it achieves it.

V tomhle díle mi trošku vadilo předhazování antikoncepce, jako něčeho totálně božího.
Dneska už přece víme, jak to funguje 🤓

Ale jinak super vtipné, jako vždy.

Sex Ed 120% volume 1 and volume 2 is a funny, semi-comprehensive and positive sex ed guide for girls wrapped in a manga with a possible GL subplot. New physical education teacher, Naoko Tsuji, is known for her brash and sometimes unorthodox method of teaching sex and puberty at an all girls high school. Despite her depth of knowledge and good intentions, she's often at odds with the school's nurse and vice principal but Tsuji is undeterred. From her first day on the job, she boldly teachers her students about how to use condoms and dental dams during cunnilingus and anal-lingus.

Sex Ed 120%'s Tsuji expressions are drawn wonderfully over-the-top to illustrate her emotions. The manga also does a great job of creating a set of female characters who are diverse in body type, sexual orientation, and gender presentation. This manga doesn't shy away from using correct biological terms and correlating them with their Western and Eastern slang counterparts. The language might make a reader blush, but the illustrations are less graphic than a high school biology textbook.

Sex Ed 120% covers more than just the physical and biological acts of sex and reproduction. It talks about consent and the nuances of consent; how the media and pornography causes body image issues in both boys/men and girls/women; and the double standard of forced gender roles. It's a book manga packed with information and humor. What makes Sex Ed 120% even more delightful is that Tsuji Sensai often realizes she still has much to learn and her sex ed lessons often coincide with her personal life. Sex Ed 120% allows the readers to learn about sex safely while expanding their view of what sex and sexuality is. At the back of the book, there's a list of references and research data so readers know that the information comes from a reliable place. This book is a 10 out of 10.

dans le tome 2, entrée en fanfare « AAAAAh, mais j’ai totalement oublié de vous parler de consentement !!! » – le titre contient « 120% » car cette prof est toujours méga à fond. Mais même quand elle parle de consentement, c’est du consentement à un moment précis – est-ce que là, maintenant, tout de suite, on a envie de sexe avec telle personne – et pas quelque chose de plus général : on a le droit de ne jamais vouloir de sexe.
En plus, en parallèle, elle est assez forceuse envers sa collègue et n’écoute pas vraiment ses refus… c’est très dommage.
La suite de mon avis (et la critique de la série complète) est sur mon blog : https://elainevker.com/blog/2024/01/0...

“Guys who pretend to be considerate of a sexual partner’s period as a way to push them for oral will be dragged to hell…”

This teacher is so extra and she cracks me up. There are some interesting facts in these books too.

The story is cute and I hope teacher and nurse end up together at some point. They are so cute.

Drží si to úroveň předchozího dílu. Jediné, co mi přijde jako přežitek je vynášení hormonální antikoncepce do nebe bez adekvátní indikace, neboť těch nevýhod jejího užívání je přece jen požehnaně. Ale uvádí i různé alternativy a opět rozšiřuje obzory. Jinak stejně jako první díl velmi dobře a vkusně zpracované.

A continuation of the first volume. Still a lighthearted, diverse, and educational series of 4komas covering sex ed, with longer manga chapters sprinkled in between.

Again, it was good, I'm sad that they don't have the third book in the library.

Still mostly informative. Still reductionist in a possibly problematic way if the reader doesn't dig deeper (e.g., regarding the side effects of the different contraception methods). Some of the humor also leans too much into borderline creepy stuff in this volume as well.

This series is so useful - it’s even teaching *me* stuff I didn’t know, so I’m incredibly grateful this exists for teens who are navigating all this stuff! And it really works as an entertaining piece of fiction as well, I’m really rooting for Tsuji and Nakazawa, and the students are all fab characters too.
