How do you determine when you've ''hit puberty?''?

In boys, it is difficult to know exactly when puberty is coming. There r changes that occur, but they occur gradually over a period of time rather than as a single event. While each male adolescent is different, the following r average ages when puberty changes may occur:

beginning of puberty: 9.5 to 14 years of age
first pubertal change: enlargement of the testicles
penis enlargement: begins approximately one year after the testicles begin enlarging
appearance of pubic hair: 13.5 years of age
hair under the arms, on the face, voice change, & acne: 15 years of age
nocturnal emissions (or wet dreams): 14 years of age.

Everything u will go through is totally normal, the above is a guideline as all boys r different most start puberty around 13yrs.

Signs of puberty - guys:
- Voice Break (Lower pitch of voice)
- Hair (Pubic,armpit,mustache etc.)
- Fast weight/height increase
- Wet dreams
- Erection
etc.

Usually for a boy u have to have an ejaculation from ur penis. It is called a wet dream. You wake up with gooey stuff in ur underwear after having a dream about girls. You should start to get more erections & have pre-ejaculatory fluid coming out sometimes. Have u started masturbating yet? Once u do that u definitely hit puberty. Did not u learn this stuff already? You in high school right? Ask ur parents, they need to tell u this stuff. Parents r so stupid when it comes to telling their kids about sex.

there are so many ways to tell when you started puberty but the most comon is getting hair down there. so i would say you hut it at 8..

yep! that means you hit puberty at 8. a few people start around 8 or 9 yrs old!!!
