There are not many signs at first but on average a boy will be around 12 when he starts puberty.
lots of ways but it can depend on the age of the guy. how old are we talking about?

Tell him you already have a boyfriend and then just walk away. that simple
High. Puberty can start at age 15 or 16, too.

No. Everybody hits puberty at their own rate, so you and your twin could hit puberty at entirely different times.
Hitting puberty at the age of 17
It means you have hit it, yes.
You can get erections any time. Hormones do it to you.
