So like, whenever I masturbate, towards the end when I'm close to climax, I start bleeding and I don't know why or how worried I should be of it. I'm 15 and I've tried to tell my mom, but she's convinced that it might just be a little infection or something. But the thing is, I don't have any pain, only blood, and it's not spotting, it like a heavy period type thing. Any ideas of what it could be or how to get my mom to take me to get checked out.
