What is a turn-on for 13-year-old boys?

Kissing, Making out, and sex Yes, and for all teenagers too. Puberty is the start of becoming a man in a boy's life and testosterone the male hormone is pumped around the body day and night resulting in sexual urges and erections. At 13-years-old a boy has just started puberty and he will be bombarded with information he cannot understand fully. This results in him being turned-on by just about anything. Pictures of scantily clothed and naked women get tatooed on the brain. His mind will keep wandering back to these images over and over again, even at times that are a nuisance to him. A simple bumpy bus ride can cause him to have an erection because of this. He will learn to control this in time and regain his composure.
