Erection Question

I have a bit of a "problem" of some sort, not really that it's a problem....

Anyway, I'm 17 years old, pretty healthy, male. I, at least I think I am, in the last stages of puberty.

When I get an erection, it seems my penis stands straight up, like it's looking at me, yet every guy I have seen naked, porn, images, etc, when they are hard, their tool kind of stand straight out, and not really straight up. When mine stands straight up, it's rock hard. I am a virgin, and when I become sexually active, I'm afraid that I won't be able to perform in some postitions because my penis simply will not "bend."

Please let me know if this is normal, or if I have a problem of some sort.

Thanks in advance.
