I masturbated last night, twice in fact, and this morning whilst urinating I noticed that my foreskin has swollen up completely overnight. This has never happened before, and quite frankly, I am scared sh*tless! I have no Idea why this has happened! I m paraniod that I may have been bitten, had an allergic reaction with something that I ve eaten or perhaps come into physical contact with. The Foreskin appears to have bloated up and is bulging over the head of the penis . It s rather freaky to tell the truth. Please reply soon. I don t want it to turn black and fall off!
