Someone please help

So I was told its totally normal for a young teen girl for start masturbating. And I was told if I use my fingers I cant pop my cherry hut Im worried they were wrong. So after I finished masturbating I went to the bathroom and little spots of blood started showing up. I meanbi just got over my period. I don't know if I accidently scratched to had or if I accidently popped my cherry. And its scary for me because Im the only person in my family that masturbates and it not a big topic in my family and I don't have anybody to talk to about it. But when the subject did end up popping up I was told by my family and friends that if I start masturbating and ended up popping my cherry I would never get married and I would be useless to my husband and sex wouldn't be fun for him anymore. So now this situation is scary for me because once it happens and it becomes a possibility I immediately start to feel useless to men and I start to think about how because of this I will never get married and have children. Please help 😭😭😭😭😭🍒🍒🍒
