I'm not sure I want to teach him the way to make me come!
MrsX, why don't you want to teach him the way to make you come? It may seem unsexy to have to do that, but what's more unsexy, that or being left sexually unfulfilled? And since you're not getting an optimal experience in the bedroom he probably isn't either unless you're a very, very good faker.
I don't understand why people are so reluctant to communicate about sex. It's the only way things can work well for members of the opposite sex together, because we simply don't know what it's like to be the other gender. And yet the difference is the source of such a huge amount of the delight! Well, life always involves tradeoffs.
It seems to me like women are more reluctant to communicate about sex. I think it partly comes from the romance novels they read. The bodice-ripping hunk comes and overpowers the damsel and magically does to her exactly what she wants without her saying a word to him. Total fantasy bearing no resemblance to the real world of premarital sex, even more outlandish than the porn men watch!
But men often don't communicate here either. I see husbands online nursing complaints about how their wives do lousy blow jobs. For heaven's sake, dude, why haven't you gently taken her aside and told her how you would like it?
