Some women never bleed.

Some women bleed several times.

Some women bleed once.

No woman should bleed every time.

What can help you is going slower and using lube; that way you won't be HURTING HER every time you have sex. Aside from her period, the only reason a female bleeds is when she is being INJURED. So stop injuring your girlfriend by using some lube.

ic ic well i duno does lube matter??? shes wet as hell so its kinda confusing, she dosent bleed alot but still

Try it and see if it helps. Are you possibly scratching her with your nails? (It's really easy to do, trust me) Or maybe going in too deep and hitting her cervix?

Try the lube, and talk to her about what it might be.

Try anyway. If she's wet and still bleeding then I'd have to honestly blame it on you being too rough and going to fast, especially if she continues to bleed every time. The only other causes of bleeding during sex are conditions and diseases that will need to be checked out by her gynecologist. She... IS going to visit a gynecologist now that she's having sex, right?
