Hello, for months I have had this little pimple looking thing on the under side of the tip of my penis. I didn't really do anything hoping it would go away but now months later it hasn't. Recently I have been sexually active and now the pimple/blister has swollen and is really tender to the touch. I tried to pop it and puss(or something white) came out. Could anyone tell me what this is and how I should handle it. Someone told me it might be something called sebaceous cysts but I'm not sure. please help and thanks for your time.
Just a lil bit ago I noticed the same thing, I am un circumsized, and have one small white pimple on the under side of the head of my penis. I have only had un protected sex twice, the most recent being roughly three weeks ago. I did how ever get oral sex two days ago. Please comment with advice
