3 days ago I noticed small pimple like red dot on my penis head. I think it is slightly raised but can't tell for sure and it's 1mm in diameter so really small.
It doesn't itch, burn..basically it doesn't do anything it's just there.

It can't be any STD since I am with my girlfriend for 3.5 years now...

I wouldn't even bother posting about it, but I am going on vacation with my girlfriend in 4 days and I don't want this thing to ruin it.

Did any of you guys had similar issue?
