My girlfriend asked me to piss in her vagina, do I do it?
gross! what kind of a sick girlfriend would ask you to do that?
you can go ahead and do it BUT it's possible she can get an infection.
so I just suggest you DONT DO IT!!
yeah you do it !! ! no girl is ever going to request you to do that again... maybe you should see what else she might want to try.
You can transfer germs by doing this.
eww no. she could get an infection
