Hello and welcome.

Ok, it sounds like you two have gotten some really awful information from somewhere.

Hymens usually tear in childhood or puberty. They tear from running, jumping, masturbation, and tampon use. So chances are her hymen has already torn due to her age. And If your fingers were in there, that is another sign that it's probably been torn all along.

Some girls do have a tough and durable hymen that does not break when they are younger, but it is not the norm. Their hymen might even stay intact after having sex! Theirs also might hurt or bleed more when it breaks.

There is usually little or no pain or blood involved when the average hymen tears, so many girls have no idea when it happened.

The hymen is not inside a girl's body; it is part of the external female genitalia. So that means it could not affect how tight or loose she is. Sex does not affect how loose or tight a woman is either. People mistakingly assume that virgins are tight, but that is not the case. Sex does not stretch out a vagina in any way. Having a baby, however, can make the vagina looser.

Many things can make a woman seen tighter or looser including how relaxed the woman is, how lubricated she is, and how in the mood she is. That can all change from day to day. Many girls might seem tight their first time, but that's usually because they are nervous, not relaxed, and not lubricated enough.

Your girlfriend is still a virgin until she has sex. Hymens are in no way related to virginity.

Chances are you just scratched her with your fingernail (that can happen even if you don't realize it, and even if your nails are very short), or that the inside of her vagina tore due to friction because she was not lubricated enough. That's very common. The inside of the vagina is made up of some extremely delicate tissue, and it can tear easily.

That's great that you two are holding off on having sex. Please learn more about your bodies before you do decide to have sex. You can always ask questions here, but here are some educational websites that can also help you get started learning:

I had had sex quite a few times and mine just tore like a year ago. Like not that long ago.

Yup, that's certainly not the norm, but it does happen from time to time.

the last explaintion was great, but i wanted you to know too, that once mt ex and i where having sex the condom came off inside me, it took a bit of effort to remove it from inside me and i did cause myself to bleed. so lil things can make a women bleed inside. just so ya know!
