It is common that when a male has a possible shot at engaging in sexual activity, he will first make sure that he has had a 'Gentleman's Shower'.
A Gentleman's Shower is much like a regular shower, but the majority of the time is spent washing the male's little cock and ball sack, rather than the entire body.
Man 1: We're going to pick up those two sluts in 30 minutes.
Man 2: Excellent. That gives me just enough time to have a Gentleman's Shower.
