I've already done some research about that and read scientific articles and such, but I have kind of a more "practical" question. My character gets kicked in his "privates" at his wedding by the maid of honor (he was trying to seduce her. Yeah, not his finest moment). At that time, he was aroused. She kicks him in the testicles, and leaves him alone. So yeah, he cries in pain etc., but that's not what I'm interested in. Am I right in assuming he would have some difficulties "performing" on his upcoming wedding night? This is happening at 5pm, and let's say the wedding night would probably begin around 3am.
Thanks for all input! I found lots of answers about sport injuries, and the fact that men have to "take it easy" for a few days (I guess with the sport), but nothing about a man being kicked in his private parts when aroused.
I did find some stuff on a forum about men saying they love being slapped very hard there during love-making, but I don't know if that is really something because there also was a lot of trolling involved on said forum.
