I think it's true that it definitely simplifies "what men want" and generalizes too much, as not all men want the same things.
However, in terms of sex, those ARE the most frequent things that at least my guy friends say they want. Though great head is usually more of a sarcastic/joking kind of thing. They may like it, but it's also not like they're saying "god the blowjobs im getting are just so boring!" it's more of a "more is always welcome *wink*" sort of thing.
The enthusiasm is probably the biggest one, and I find it the most agreeable as well. It's not just that he needs his ego stroked or whatever. I mean really, would you enjoy having sex with someone who didn't act like they cared or enjoyed what was going on? It may seem silly as this is EF, so there probably aren't too many people around these parts who can really relate to the level of disinterest MANY women show for sex. It just doesn't feel good and isn't that fun. It might seem silly to us, but trust me, there are many many many women out there who need to be beaten over the head with something telling them to enjoy themselves more.
Or maybe they're all just unknowingly asexual. No idea. Either way, it's no fun to be with someone like that if you, you know, want to enjoy sex with your partner. Overall, I don't find it that offensive.
