The scissors position: She lies on her back, he lies on his side on her right (because most of you will be right-handed and he will need one of his hands to stimulate her clitoris, so use your better hand; if he is equally adept with both hands, then it doesnΒ΄t really matter unless his penis is not straight like a candle and hits her g-spot better on one side than on the other). She then pulls up her right knee to her chest, he also pulls up his right knee horizontally so that his right thigh comes to rest on her left thigh; his left leg passes under her left leg so that he can straddle it with his legs (the last bit is not a must, but this ensures that his penis wont slip out of her vagina during sex which can be annoying, especially when she is just having her orgasm).
This is it as far as the basics go. If left at that, however, it would just be a new position at best, but whatΒ΄s so special at the scissors position is that it allows the male lover to give his female lover additional pleasure in many other ways while having sex, and this is what he should do if he wants to truly satisfy her.
