An orgasm which is given out of an uncomfortable sense of duty; much like parting with small change when confronted with a bucket shaking Salvation Army worker. You don't want to give it, but you'll be made to feel a total shit if you don't.

Here is a typical example of a circumstance that requires such a donation. Your partner has been moaning all the livelong day about their appearance. Words like "obese", "disgusting", "hideous" and "gross" have been used so often and so emphatically that, despite yourself, you genuinely begin to agree. Then the obligatory "You're so gorgeous, I can't keep my hands off you" sex that was meant to assure them they're hot has become an act of charity, with you performing deeds that you would rather not share with someone who has half convinced you they're a troll.
