Defining a "money shot" as a moment when someone pulls out of fucking to display the ejaculating penis -- I've *never* seen it written baldly just as that, in umpty fandoms with oodles of NC-17 stories over twenty-plus years. This is why I've answer no, no change, and not checked any boxes in the poll questions. I don't go looking for it as a kink, and in general avoid stories that evoke any ambience of commercial porn, but I'd probably have seen it *sometime* if it were at all common.

On the other hand, slash writing where the sex features hand jobs and the like, where the inevitable ejaculation is described in loving detail as well as the reaction of the person it lands on, are not at all rare. Are you including those in your definition? They lack the jarring, counter-intuitive falseness of pulling out for the camera at climax.
