Is it normal for girls to pee on themself

It's normal, I do it all the time.

I do it. Love it too.

I've honestly never pissed myself intentionally. Maybe when I was like three.

a lot of porstars do it

Yes, there are many sub genres of the pee play fettish ie; golden showeres, self wetting, and more. Message me, kik or Skype and I can share more.

voluntary? or it just happens while taking a piss?
BTW in most cases squirting is piss :3

Voluntarily
