When Will I get more penis hairs and arm pit hairs.?!

It takes several years to go through puberty, not several months. There's nothing you can do to speed things up, so may as well relax and enjoy the ride. Unless you're trying to contest with other guys, there's really little point in worrying about your changes. More pubes and pit doesn't make you any more of a man than fewer.

The main thing is that everything is in good working order.

btw, random boners are par for the course when you are a teen. There's no logical explanation for them. Sometimes someone hot will trigger one off, but mostly they have a mind of their own, and pop up without warning. Hence, 'random'. If it helps any, virtually every guy on earth has experienced it.

Well it is possible, but different guys develop differently, some faster and some slower. Hard to tell but usually once you start it moves along fairly fast till toward the end and the it will slow down.

I'm hoping the same thing, got pubic hairs and no armpit hair, well if i look really closely there are small ones, heck my voice aint changed yet. Lets both hope it happens in summer :/

Your okay the way you are,
