Size of the penis is not so much important, as a knowledge, how to use it but if you want to penetrate deeply possible in your female partner, this position would come in handy. The female partner lays down on her belly and slightly lifts the upper part of her body on the elbows, opens the legs apart. The male partner sits down between his female partner’s legs, putting stress on his knees, along with this, he is taking one leg of the female partner, sets his thigh forward and throws his leg on it without taking off his hand. In practice it is quite interesting, don’t hesitate to try it.
