rehearsal dick

The old dick you have to get, before you get all the new dick, because it's been a while since you had dick, so you have to reacquaint yourself with the ways of dick.

"We're definitely gonna have sex soon...I'm nervous though, I haven't had sex in aaaaaaages"

"You need to get yourself some rehearsal dick first, reacquaint yourself. Get the old little black book out."
