Try this tantalizing twist on the typical missionary position (him on top, you  on bottom). Instead of having your man rest on his elbows, ask him to slide two  to four inches forward. Have him place his arms on either side of your  shoulders, letting his body fall flat against yours. Make sure you both keep  your spines straight. With your legs touching his, push your pelvis up about two  inches. Your man should push down gently, providing a little counter-resistance.  Instead of the usual in-and-out of thrusting, rock up and down.

Okay, so missionary doesn’t always make you quake. But because he’s in a more  forward position, the base of his penis should naturally rub your clitoris. The  rocking motion draws out the orgasm, building pleasure gradually. Because both  sets of genitals are sharing such tight quarters, your climb to the climax will  be intensified.
