I'm 18 and still a vergin. i once fingered my girlfriend and masterbated with that hand after she left. i dont remember washing my hands if that is related to my problem. so i had this small bump on the bottom left side of my penis. i tried to sqeeze it and didn't pop, aslo it didn't hurt. next day the bump got huge and i waited 2 weeks after researching and it became a huge pimple. still no pain.. to day i accidentally popped it. I didn't know what to do so i kept sqeezing it. until it puss was all out.. i'm afraid.. really really really afraid.. i don't have medical insurence yet... and i have no idea where to see a doctor. please.. please explain to me.. what this is.. and if it is harmful and how to treat it. doc..
