hello
for the past couple of weeks i noticed a very tiny red bump on the side of my penis head. it almost looks like a blemish
there is no pain or discomfort and no smell what so ever

I haven't been sexually active for quite some time now at least a year but i do masturbate once a day or once every other day. since this red spot developed i have been masturbating even less out of fear of agitating it.

i'm very clean and take showers once a day. could someone tell me what this is?
is it just skin redness from masturbation?
thx for the advice
