Tell me about normal penises!

Being a teenager, you can imagine I'm very panicky at anything remotely strange.
To cut a long story short, when I'm erect and lying down, my penis goes right back, to the point where it pretty much touches my stomach. When standing, it's pretty normal, it goes slightly upwards however, but I'm not to concerned about that.
So is it normal that my penis is like that? Also, will it stay like that forever? I fear this might get in the way of sex. Can I do anything to change it?
Thanks.

Some people who are fully erect have wieners that point down. I don't think there is such a thing as a normal penis. They come in all colors, shapes and sizes brother! Be proud that you are a wiener wielder of power!

It's normal. Some people have them curved to the right or left as well. A curvature can actually benefit a a woman during sex. And before this thread even has a chance of getting out of control, I'm shutting it down.
