Hi
I know that hymen covers the vaginal opening. Whether the hymen should tear so that the vaginal opening will become bigger??

Vaginal opening looks small,whether it becomes big during intercourse??
My husband's penis foreskin doesn't retract much during intercourse.

Do you think this may be a problem for successful intercourse?. We couldn't make successful sex life.so please give advice.

PLEASE EXPLAIN ME ABOUT HYMEN ,VAGINAL OPENING AND SUCCESSFUL INTERCOURSE.

Thanks
