Sometimes we'll be busily humping away and my wife will murmur, "Oh, I want you cum. I want you to cuuuum." I find this very exciting; in fact the utterance is often enough to make me cum.

It's as if she's commanding me to cum, which drives me wild. I like thinking that she thinks of me as something utilitarian, a machine whose sole purpose is to service her.

Several times I've told her this afterward, but she tends to laugh it off. She says she wants me to cum because it feels so good for her, and because she's looking after my pleasure. She seems to pooh-pooh the idea that she would use me as an object to be used for her pleasure.

And yet the thought of being nothing more than that, at moments, is so insanely arousing to me . . .

After keeping my pubes trimmed throughout the summer, I'm letting them grow back in. I trim them mainly for comfort in the hot weather, but my wife seems to prefer the "full" look. She likes to run her fingers through a full bush and seems to enjoy burying her face in it. Can't say I object!

It's been my observation that women enjoy greater variety than I do in the way in which they're sexually stimulated, but I don't know if my narrower preferences are unique to me or common to all guys.

The women I've known can be unpredictable: One day they'll want their nipples sucked and the next day not; one day they'll want to be fucked fast and furious and the next day slowly and gently; one day they'll want their clitoris licked and the next day they'll want me to move right in with the cock.

I, on the other hand, usually like the same things: having my cock and balls played with, having my cock sucked, having my ass grabbed and squeezed while I'm fucking her, having her caress her clit and caress my balls as I'm fucking her from behind.

This is not to say I don't enjoy different positions or fucking in unusual locations. I like changing things up for the sake of variety. But the ways in which I like to be physically stimulated don't vary a whole lot.

Don't get me wrong: I love the unpredictability of women. That's part of the tremendous delight I find in them. But I'm wondering if my experience is the rule or if my preferences are singularly limited. Do women enjoy and expect greater variety than men do? Are they less predictable?

Gals: How did you learn to stroke and suck a cock? Did some thoughtful guy give you instructions? Were you given gentle corrections? Did you learn from watching porn?

I remember a gal who thought she was supposed to squeeze rhythmically, so I showed her that, while the squeezing was nice, a nice up-and-down motion without too tight a squeeze would work better.

Guys: How did you learn to caress and lick a clit?

I learned by watching movies and then by getting feedback from those I tried it on. Most women seem to absolutely love having their clit licked, but manual stimulation can be a little touch-and-go. You don't want to rush it, and you want to make sure you have sufficient lubrication. A gradual, teasing approach sometimes seems to work best. After she has one or two orgasms, I like to move in with the tongue and then, when she indicates she's ready, with the cock.
