Im an 18 year old virgin but i have masturbated before. This is the first time ive bled masturbating. I masturbated with an oversized pen (like a really big one) and I took the ink out beforehand. After a little while, It hurt a little but I'm not sure where, but I stopped. I realized there was blood on it and some clumps of stuff. It bled for a little while and now about 2 hours after, I put a tampon in waited an hour and then pulled it out - to see where the blood was coming from. At the top of the tampon there was some blood all around and at the bottom there was some blood all around, nothing really in the middle tho. Should I be concerned? Was it my hymen breaking? I'm not due for my period for 9 days. Like 24 hours ago, I had random cramps that I assumed was from ovulation. I don't really want to tell my parents but I'm terrified this is serious. What could this be and how long should I wait and see before telling??
