Okay so... about a week ago I had some fun with my girlfriend, but after I'd started to bleed. But I just ignored it because I thought it was completely normal and that my cherry had just popped. It'd make sense because that was my first time. But today I tried having a little fun on my own, but I stopped when I pulled my fingers out and saw blood. What made me stop is because I thought I'd came, so I was just going to stop. But it wasn't cum. It was blood. I immediately stopped and put a pad on and washed my hands. Should I be concered, and does anyone know what might be going on with me?
