Never make a decision regarding a relationship while under a sexual trance. Rub one off and then decide on what to do about the girl who thinks that it "must be more than a booty call"
"I was going to date Sheryl, but a good ol' wisdom wank through that out the window".
When a person has thoughts of cheating on their significant other and they masturbate to relieve their lust and return to clear, rational thought; usually realizing that cheating is not worth it.
The only thing you need to stop you from cheating is the Wank of Wisdom, because cheating is not okay.
