It really shouldn't matter.
If your ashamed about it talk to your doctor they have some procedures that they can do to straighten out the penis. So in my mind if i were having this problem i would talk to my family doctor or any doctor
Only a woman can tell you for sure - it might help, it might hurt, it might make no difference. In any case, don't worry about it, and don't make a big deal about it. When the time comes, you can bring it up with the right girl. In the meantime, tell your cousin to mind his own business.
Actually, the upward curve may very well put your penis in the vicinity of a very stimulating part of the womans vagina. I would talk to your partner about that but the shape should not be anything to be ashamed of. You may very well have a gold mine between your legs!
