What happens if your penis is to big for the vagina?

The vagina stretches and even a baby can pass so it's not about the size of the penis. The woman has to be properly aroused and naturally lubricated and swollen inside. if not, it will hurt. Lube out of a bottle will never replace the real thing. it can also help if she has a orgasm first before he enters and if she is on top and in charge. Some guys also like to go all the way ion and that is not always possible if he is long. He can hit the cervix which can cause pain or discomfort. the woman decide how deep he can go which is when she being on top would be good.
