My penis slips out during intercourse. How can I prevent this from happening?

The best way to prevent the penis from slipping out is to enter the vagina deeply and make short movements. So don’t draw your penis back too far, just one or two inches. Make sure a few inches of your penis always stay inside the vagina. Furthermore, you should synchronize your movements, you and she moving together and not in opposite directions. If you draw back and at the same time your lover moves her body away from you your penis is bound to slip out. Try positions in which your bodies are close, like missionary, doggie style, amazon or lapdance. If you do it in the missionary position you girlfriend should wrap her legs around you. If the penis slips out anyway, it’s easiest if your girlfriend immediately directs your penis back in, using her hand.
