Today i was walking my friend hit me in my balls with a bottle pretty hard and now my penis feels weird. it feels like it shrunk if that makes sense. ?

Here are some...: If the pain after the hit became bearable and getting better and better in 1-2 hrs despite maybe seeing possible bruise, that will be okay to wait out with time and patience. If severe unbearable pain last reaching its peak in 30 minutes and staying and lasting..., seek evaluation with scrotal US so to ensure no tension inside testis from its internal bleeding... So, you decide when & how to deal.

Pudendal nerve: One or more branches of the big nerve down there got bruised. Should heal okay. You're almost a grown man, Eric. As a teen, I enjoyed rough-housing and "playing tough" with friends, but this stuff is dangerous. You can end up with testicular torsion, or an injury that would excite immunity and keep you from being a father. Cherish your friendship and find other wholesome ways to bond. Best wishes.
