There is nothing
annoying about it. It makes
urination very easy. It doesn't hurt at all when kicked, and can shield the
testicles from such assaults.
Well, OK. When you are young it can be annoying, because it needs occasional adjustment... but once it attains sufficient flaccid mass, it stays in one place. Adulthood is permanent.
It is low maintenance compared to a vagina. You have to have genuinely bad hygeine to get a yeast infection. It is not naturally moist so that and other infections have a hard time gaining a foothold. The turtle neck configuration has to be thoroughly cleaned every day, of course, but daily bathing is the norm in modern culture. The crew cut configuration is highly resistant to infections of every kind.
As far as the argument that it looks "silly" or "awkward", pfffft... Whatever. Function over form. I mean, really, just what the hell do you want it to look like?
Re: Dolphins and retractable penises... Human females have exposed genitalia. We don't need prehensile dicks like a dolphin does. (They would certainly be cool for PARTY TRICKS...)
