I've had this red/pink bump on the shaft of my penis for 4 or 5 days, and today it's bigger than ever. It's about 1.5cm in diameter, and has a small orange-ish tip. It's not sexually transmitted. What do I have? Should I go see the doctor?
Always see a doctor when you have something going on down below. It could be nothing with an easy treatment. I’d get it checked out.
