Slept with someone way younger than me

Nobody at work knows, but a coworker (22F) started texting me (37M) late one evening and wanted to hang out. I knew where it may be heading and I was very excited. We hooked up and it was great. We actually hung out casually a couple times that week and hooked up again a few days later. She seems very promiscuous and I think has already moved on from me, but man that was fun. Things are a little weird at work now but I hope she hits me up again.
