Not sexist, sadly accurate in most cases. I'll be the first to say that I love to put all of the effort into it that I can, but especially after years of someone who would kiss me once, roll over on his back and say "I'm ready" (I kid you not) I have discovered that even when I put barely more effort than he did into it, the desired effect (for him) was still achieved. I'm not even freaking hot, and I just managed to stand in for a right hand without any effort, woohoo :S.
On the other hand, the one I'm with now has discovered one of the huge secrets, which many men, who are stereotypically much more physical than emotional, haven't a clue about. Like many women I have a bit of a low self-esteem, especially on the physical aspects, yet my SO has learned how to make my insecurities seem completely silly to me. If women feel hot they tend to stop being self-conscious and start really enjoying being able to induce as much pleasure as possible. It doesn't work just to try to convince them they're sexy when you're in bed and sex is imminent, because if that's the only time they'll stop believing you.
That, combined with some amazing physical skills and attributes, and the willingness to put forth effort and a desire to please (yeah guys, this is a complicated recipe
) have made him absolutely amazing.
