So... for at least around 2 years I've had this blood blister on the underside of my balls. I dont' know how it got there, it could have been from someone tap-sacking me. I am not sexually active, and I don't believe I have landed on my crotch anywhere.
The area around it has blood drawn to the surface, almost like a hickie (but it's not ) and every time I've popped it, it just bleeds for like... forever, and then it's still there the next day. I've tried popping it then covering it with bandaids, toilet paper, and even soaked in the tub for a long time. It bled the entire time.
