1. Puberty sucks, but if you are going to be a man, the first step is to stop whining about. Every person goes through it, you arn't special, and puberty starts for most people around 10.
2. You are too young to be taken seriosly here. Not simply because people disrespect you for your age, but because you are too young to not look like an ass here. There is an age requirement you don't meet, but i'm not a mod, it's not my problem to deal with.
3. If you are getting random boners, just think about something that you find to be the opposite of sexy, and it should go away soon enough, sometimes even before you get a boner in the first place.
Imagery is a useful tool.
