I am very scared. I have recently found a bump on the bottom of the shaft of my penis. I am a teen in the last stages of puberty. It is a red bump and it feels like a ball when I touch it. Can someone tell me what it is please, I'm very worried and anxious.

Ummm well, it is from masturbating. Don't fool around with it, don't try to squeeze it, it will go away.
