I have a tight hymen. I never bled when i lost my virginity, but i bleed frequently from a hairline tear you can see on the outside opening. Its like when you split your lip a little and it bleeds. Usually heals within a day or two for me. While bleeding can indicate something is wrong, it doesnt have to mean something is wrong. I am in close touch with my gynecologist who has ruled out any other problems. Im just tight and have a tighter piece of tissue that covers the vaginal opening that will only stretch so much, its just never given me major problems until i got with a well above average girth man.
Taking the advice to see her gyneologist is always the way to go, she might have a tight hymen like me and stretching to a certain point can cause bleeding. Also, my cervix can bleed a little for my yearly exams, i suppose you can have the same thing happen if you were to hit the cervix to hard and she was prone to bleeding.
See the doc to rule out problems, but this is something that i've had to live with for 9 years, vaginal estrogen treatments, manual stim prior to intercourse and lots of lube helps a little, but doesnt change my anatomy. She can find out whats going on at least.
