Hey I am 14 years old, and I am also in the mid stages of puberty. This is kind of embarrassing but I have a small bump on the left hand side of my penis and I was wondering what it could be. Here comes the super embarrassing part; I just got done masturbating about an hour before I went to go pee and I noticed the bump and I was wondering if it was from irritation or what. Should I see a doctor? Oh, and I am a virgin.

It is from the irritation.
