I'm not asking how biology works at this point. What was by this point in the thread was ways to get Tab A into Slot B without it seeming unbelievable, and I think I made that quite clear several times. I had a long talk with mi'lady (who is also my writing partner) and we might have something cooking up. So far, I think the idea of "revenge sex" is close to the top with "drunk one night stand" coming in a close second, followed in third by "sloppy make-up sex" with her previous hetero relationship.
