Yes, I did read this for the sex and it took me many years to figure out the serious point of the book. I would say that it was a satire. About our culture's focus on sex and beauty and our willingness to "overlook" some serious downsides. I think that Joe's officer pal was a stand in for the author who I'm guessing is homosexual but who knows? The officer certainly was. There's probably more to it than that but I read this a long time ago. It certainly doesn't present a very flattering picture of women. Date read is a guess.
