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.
