1. Happens when two males stand next to each other to urinate, usually they cannot. This is called stage fright
2. Happens usually on first time intercourse but can happen in other times of intercourse...
When the male wants to have intercourse with the female, but his penis does not.
Instead of staying/getting erect, his penis denies him the privilege.
Boy: Errr Yeh!!
Boys penis: PENIS SAYS NOOOO
Boy: Your such a dick
Girl: Awww you've got Stage Fright!!
Telling them to hurry up will only prolong the experience.
They: Stage Fright.
You: Damned Freelance Bladder, we're only going around the corner.
