DAVE C., FLThose Calvin Klein and Abercrombie ads featuring 18-year-olds with rock-hard six-packs haven't escaped our notice. Young guys without demanding careers have lots of time to hit the gym--we know this because, unfortunately, they seem to talk about it more than anything else. But their inexperience can be a pleasure. They treat a woman's breasts as if they are precious archaeological finds. (The vagina, on the other hand, is beyond their comprehension.) And they love to make out for hours, an area where older men seem to lose their appetite. Would I rather sleep with a man my own age who has a great body and a predilection for kissing? Any night of the week.

DAVIS, BOULDER, COClothesline her, stupid. Just kidding. You can't stop her. All you can do is keep her in your sights and be there when she slows down. Then pop the most innocent question of all time: "Excuse me, do you know what time it is?" When she answers (even if it's, "Sorry, I'm not wearing a watch"), say, "God, why does time go by so slowly when you're running?" What you're really doing is letting her get a good look at your friendly eyes and sweaty physique. If she likes what she sees, she'll make conversation. If she doesn't, she'll give you a short answer, smile, and move on. Short of clothes-lining someone, that's about as painless as it gets.

ANONYMOUS, VIA E-MAILEverything. But start with this: Lay her down on her stomach and slowly rub massage oil into her shoulders and back. Work your way down her body, spending extra time massaging her bottom. Turn her over and rub oil onto every inch of her skin other than her breasts and pubic region. Remember, the longer you tease, the better. Finally, lick and kiss her nipples while your hand slides between her legs. Stroke her clitoris gently with the pads of your fingers using a circular motion, increasing the pressure slightly every few minutes. After a good 10 minutes of rubbing, slide the index finger of your other hand inside her, up against the inside front of her vagina. Press and release as if you're gently pumping up a pair of early-'90s basketball sneakers. After several minutes, maneuver her on top of you cowgirl style and, guiding her hips with your hands, encourage her to grind back and forth against your abdomen while your penis is inside of her. At this point she's in the position that makes most women orgasm the fastest, and after all that stimulation, she'll be as ready as ever to let go.

HARRY, NEW YORK, NYTake it as a good sign. The fact that your girlfriend enjoys being reminded of the past probably means that she's had mostly positive, healthy experiences--making your prospects for the future more promising than if there were no evidence of her romantic history at all.
