Okay we all know that all virgins have a hymen which partially covers the vagina.

My friend who is a virgin did a physiacl examination of herself and found that the hole which leads to the vagina is small. She does see her period normally, but

Because of this, does it hurt during sexual intercouse for the first time becaue the hole (diameter) is smaller than the average penis in diameters. Does anyone knows any web site to show what the hymen actually looks like.

Can you provide any more information on having sex for the first time.

Actually no, at least in America culture because of some exercise, tampons and other things, many women have the hymen broke long before first sexual contact.

And even so, there will still often be some pain and bleeding on the first time.
