I'm 16 and I never had sex or oral sex and I have this small pimpel like bumb on the end of my shaft, not the head but near my testes and it has been there for about 2-3 months. It looks like a whitehead and I scrach it off and it still comes back and it wont really pop. I don't think it is an STD and I just want to know what it is and how to get rid of it. Thanks.
