Hi. I'm 17 and a virgin. A few days ago I noticed a red spot with a yellow (Pus) centre at the base of my shaft. Since then it has risen, but is still only about 1cm (maybe less) in terms of width.
I haven't gone to a doctor or anything yet since I haven't had any real pain from it. I need some advice on what you think this may be.. I'm just hoping it is a common spot that will go over time. But I'm sure you understand that I just want to be sure.
