I Was Playing With My Penis In The Shower And

I was playing with my penis in the shower and when I was fully erected I tried to insert a cotton swap inside my penis and when i was about an inch inside blood started coming out, I don't kno what happened maybe there was a sharp edge on the plastic part of the cotton swap or something, but I am scared I bleeded alot for 2 minutes and then the bleeding stopped, its been a week and I have urinated normal and clean, I also masturbated several times and everything seems to be ok, but I am still worried abouty urethra, Will it heal on its own, and should I worry about consequences???
