Bleeding during sex and masturbating 🙄🙄

I feel like I always bleed when I have sex. It's always been a problem for me. Wether I'm on my period or not somehow I always end up bleeding. I have a clean bill of health, no diseases or medical problems. But even when I rub my own clit and make myself cum like three times that way, I start to bleed a little bit... What the fuck? Does anyone else have a problem similar or have any tips?
