I hve a very small penis my friends make fun of me and I am turning 13 already how can I solve this for a bigger penis my ex broke up with me because I said no to sex so pls what can I do to get a bigger penis.
You can wait. You've likely just started puberty.
Your friends are also probably small. There is no real average below 13. Why? Because many guys are just starting puberty. Average for a 13 year old is 3" erect.
Your penis can grow into your early 20's.
