i was just masturbating and for some DUMB reason i grabbed one of those syringes full of teeth whitener(no needle) and injected the stuff into the head of my penis, the urethra or whatever. it doesnt hurt, there is a very slight tingling feeling but it is not bad at all and totally tolerable, but the head of my penis has started too kinda bulge up in places and become a lighter color, making the head look...deformed i guess. this was like 10 minutes ago, what should i do? it was 22% carbamide peroxide and after looking it up it says that 10% wont do anything to you but 35% will burn so im guessing im in the middle...but will the swelling on my penis and the discoloration go away after a shower or just overnight or time in general? i know im an idiot.
