Okay so today I was in an area with friends and I decided to go into some trees to "take care of business". I was doing fine until someone wandered up to where I was and startled me. So rather than pulling up my pants and peeing myself I tried to stop the flow of urine and it hurt all of the sudden so I let go. But now about 2 hours later, I masturbated and noticed a bit of blood. It didn't hurt though until I urinated afterwards. My primary concern is permanent damage from this stupid incident. I am 21 and feel I'll heal okay but my paranoia is bugging the c**p out of me. I'm wondering if someone with better information on the matter could help me out with possible ways of tending it carefully or to set my worries at ease. Is so it would be much appreciated.
