Fetish which involves one of the people having sex being completely apathetic about that fact (and will usually be focusing on something else or be showing overt signs of boredom), with the other character(s) providing all the enthusiasm and possibly getting off on that aloofness.

There is some overlap with casual sex, but not all are the same fetish.
