What happens when it wold be considered rude not to have sex with someone due to a sense of expectation or obligation.
Stormy wasn't remotely attracted to Donald, but she really wanted to leave, so she gave in and had courtesy sex with him.

when you start rubbing your partner to initiate sex but are hoping they don't want any because you are too tired to perform. so you can say the next day that you tried to but your partner said no.
I tried to turn him on by rubbing his cock, but I was so tired it was actually just a "courtesy rub"

Courtesy Flash: Occurs when a strong, strictly platonic, friendship forms between an average male and extremely attractive female. The male wants to bang the female incredibly bad, but usually the female is hung up on ex-boyfriends, or too emotionally unavailable for the male friend to take advantage. Under these circumstances, the female will need the male friend to reach out to, and in turn the male friend will keep trying to bang the female, because of the attention he is receiving from her. The female will recognize this, which will make her feel ill of depriving this weary emotional soldier, her good friend, his sexual dues, and will reward him with a random flash for the time he has put in. Thus the Courtesy Flash was born; to repay the male who has no chance of banging the one he desires, yet just deserves to see some fuckin' amazing titties.
Davon: So I Laura and I went to the lake yesterday, she and I are such great friends!
Mika: Holy shit dude, she has the biggest cans I have ever been in the presence of.
Davon: Damn, you're right. I want to bang her so bad it's all I can think about. She keeps teasing me with the courtesy flash. I can't just ignore the possibility of seeing some grade A boobies at random, just for talking about her ex boyfriends new girlfriend. Her boobies are so nice.

When one finds oneself in a situation "south of the border" with a lady....and the "situation" is not a place you care to be. In other words, things are bad (ie. smell, presence of discharge, discolouration, etc.) - very bad. In such a case a "courtesy" lick is given to the area in question followed by a similar lick of the thumb and subsequent manual stimulation of the clitoris (w/ said thumb).
I started to go down on this chick and she was super hot." "However, the state of her genital region required the use of a courtesy lick.

When a group of one sex encounters an attractive member of the other sex, one of them must flirt with them as an acknowledgement of there attractiveness.
Me and the guys were out last nast night and we came across Jenny who was looking phenomenal, so Adam gave her a courtesy flirt just so she wouldn't feel slighted.

When a male continuously strokes the clitoris of a female vagina with his knuckles, while at the same time he masturbates.
Last night a-dog and I had sex at the montage. As he pulled out he began to masturbate and give me courtesy knuckles. It was a blast!
