When a man is so sexually excited that he runs a hot bath and only puts the head of his erect penis in, which makes him cum imediately into the hot water. Masturbation, sans the mess. Also, more discreet.
John had a huge boner, but he was afraid to have his parents here him jack off, so he went water bottling.
