So just 3-4 days ago, a small pimple like thing appeared at the base of my penis shaft. It has now grown in size after applying an antiseptic to it. Does anyone know what this is? Should I be concerned? I am not sexually active and I am 16 years old. Anything will help.
looks like a large pimple or boil
try putting warm compresses on it to bring it to a head
It would be fine, it would heal itself. It is quite common if you live in tropical or warm climate.
