midlife crisis

i swear i never thought about this kind of thing when i was still married or anything but lately just thinking about it so much. had this one time with a student back in my twenties, he came to me for advice and ended up asking if i wanted to explore something more, yeah sure why not? kinda like being surprised by the whole situation. didn't get involved though, he was still too young i guess. but now with everything going on in my life it's like... what would happen if someone did want to do that again? and just as an experiment or whatever, because there is no way anything could come of that honestly. so confusing.
