>>13287931Dolphin genital evolution is fascinating, and has a lot of parallels with ducks. In both cases, females have evolved extremely complex vageens which enables them to divert the male's cock into various dead end passages. This is presumed to be some sort of evolutionary arms race in response to how common it is for males to force matings with unwilling females - females have some ability to limit the possibility of conception when they're being raped. Males in both groups have in response have developed cocks of terrifying size and complexity to try and get around unwilling females. Dolphin dongs are not only huge but slightly prehensile.
Dolphins definitely ejaculate with significantly more force than a human does. I think the memes on the internet about it perforate organs are probably exaggerated, but I wouldn't recommend trying to fuck one.
