Well on my penis i have white pimple like structure that smell like fish or close to it. What could it be? Am uncut, never had sex before nor anything that could deal with me getting stds. Since I also am uncut my skin is very tight and cant get it to go all the way big, what can I do..am sacred it might hurt the 1st time I have sex. Sounds like am a kid but am really 19, am so behind in the "sex world"
