Okay I am a 18 year old male,circumcised and since I was 15 I got these little pen drop sized pimple looking things around the corona of my penis they have never gone away never gotten bigger or smaller,they are flesh colored and sometimes red,get red when I'm erected ,no boils,no warts,no open sores,no blisters or anything like that.When I was 15 I only had sex one time with my old girl friend and I used a condom,didn't have anything after that,when I first got it I would Masturbate a lot back then and I used soap to do it and didn't wash it all of or sometimes shampoo and didn't get it all off,and my penis got those little pimple looking things around the corona and around my shaft shed after that I didn't use soap or anything anymore.I still have the pimples 3 years later they never gone away never gotten bigger and never spread,My question would be is this an std,a yeast infection,or balanitis?
Please help me
Thank you
