Let me explain. I'm a boy, and I'm going through it right now.
First, Boy Puberty doesn't hurt at ALL. It's just uncomfortable. Its really strange because you get erections so frequently, its not even funny. Not because your are thinking about having "it" with a girl or thinking of a really hot girl or someone you like, sometimes your ahem, penis has an erection out of the blue. YOu can be thinking of nothing, and then all of a sudden you get an erection. I hate it, because it is sooooooooooooooooooooooooo embarrassing.
However, there are some GOOD things about boy puberty, hard to believe, but you start growing muscles and the muscles you already have get BIGGER and you get really tall (known as Growth Spurt). So most girls like when guys go through puberty because they, ahem, look sexier. It is nice having bigger muscles. This is the part of puberty I enjoy. Your upper body (mainly chest) get bigger and you look more muscular.
Don't think boy puberty is all fun. There are some BAD parts about it. First of all, your...penis....gets bigger and it gets in the way. This is bad because that means bigger and longer (both size and time) erections. It gets so big sometimes it gets in the way.
Another BAD part is that you grow pubic hair on your....um...base of your...ahem, penis. Pubic hair also builds up on your....testicles, and let me tell you, it is ANNOYING! You also grow hair all over your body (mostly armpits and legs) and that is also annoying.
Another POSSIBLE side affect of guy puberty is acne. That makes you look ugly.
Here are some, well, what I think are GOOD side effects. Numbero uno, you start REALLY liking girls. Like all over it. And that reassures you that you are not the g-word.
Lastly, your voice gets deeper. I like it because my voice has always been on the high side.
This can start from 9 to 15, so your fine.
hope this answers your question!

EDIT:
You will be ABSOLUTELY FINE! You are on your way! Just wait it out because there are some people who were 16 and still puberty hasn't set in yet. Hair on your, ahem, means that you are starting to go through it. Just wait until you are 11 or 12, like I am and soon it will slowly start coming.
P.S.-I kind of like going through male puberty. It's kind of fun because it's just your body maturing.
