Anybody who’s so young to still be calling their penis a ‘peepee’ is probably too young to get hard erections yet. (And shouldn’t be on an adult site like Quora.)

And anybody who’s old enough that their penis gets hard probably has a good idea what’s causing it to become hard

It sounds more than just a little silly and childish for an adult male to be calling his penis a ‘peepee’.

I call ‘troll’ on this question.
