I've made an unofficial contract with myself, for every time I orgasm without my fiancee, I will do 30 sit-ups and 20 push-ups. I don't know if I would call this reaction a guilt thing, but I'm wondering if other people have similiar habits.
For example, I knew a guy from undergrad who added change to a jar everytime he jerked off.
