IS THERE AN IDEAL ANGLE FOR SEX FROM BEHIND?

Put away the protractor, Phil. There are too many factors involved to single out a surefire angle. In general, I’d limit the classic hips-up/head-down position, which can overstimulate you and expose her cervix to thrusting. Your best bet could be to ask her to keep her back straight, which will relax her vaginal grip and allow you to tap her G-spot with downward thrusts. Every woman — and man – -is different, so experiment to see what works best.

MY GIRLFRIEND SAYS HER BREASTS ARE TOO BIG TO HAVE SENSITIVE NIPPLES. CAN THIS BE TRUE?

Sure. Larger breasts (C or D cups) are generally less sensitive than smaller ones. It’s thought that there’s some nerve-fiber damage associated with stretched skin and connective tissue. But don’t despair. Though the nipple and areola–which many men focus on–are low on sensitivity, the top of the breast is highly sensitive. Explore her northern hemispheres or, if she’s game apply oil to her nipples and areolas. But if she’s not aroused by breast play, move on. You have an entire body to savour.

MY ORGASM IS BETTER WHEN SHE’S ON TOP. WHY? WHAT OTHER POSITIONS SHOULD I TRY?

Start by figuring out why this position excites you so much, and learn from it. It’s possible that the wow factor comes from your better view of her — being able to see her breasts bounce or the way your bodies move together, for example. Or maybe it’s because she’s more in control and able to vary the pace, slowly building your orgasm to its powerful potential. If you suspect it’s the visual cue that does it for you, have her straddle you on a chair or place a full-length mirror against the wall near your bed. If you think you’re more excited by the gradual build-up to orgasm, try side-by-side sex, which can prolong the anticipation.
