Is it wrong I (53) hooked up with an (18) guy in high school?

Last night I met a boy on Sniffies to come over and bottom for me and everything was great. Afterwards, he said we should hook up again so I asked him when he was available. He said weekends or typically anytime after 4 on weekdays because of school. I asked him what he was majoring in and thats when he said he was in high school nearby. I felt mortified in the moment about what I had just done. Then I realized he's an adult like anyone else and old enough to make his own decisions but I still woke up thinking about it. I've hooked up with a couple of 18yo in the past but none were in high school to my knowledge and I don't know why that matters to me. When I was a horny teenager his age I frequently had older partners but I don't think any were nearly 3x my age. He is a skilled bottom and his body is physically fit and mature so he could've easily fooled me and pass as mid twenties.
