Im 15 years old and over the past couple of months i have noticed a rather large red spot with a kind of white head on the head of my penis. Its painful when you squeese it and it is very annoying. I have not ever had sex before so it carnt be an STD (it carnt be inherited either). It sometimes shrinks in size but then it gets worse and vice versa. Please help me, dont tell me to go to my GP or GUM clinic because i am too embarrased.
