I’m 20yo and I’ve been with a 64yo

This started some months ago since I was bored, depressed and lonely, I met this guy through a kinky app and we met days after. He was nice with me the whole time but I felt I was doing the wrong thing by being with him. Anyways we end up having a very close relationship, we started fucking and doing some kinky stuff too. It’s hard to admit but I enjoyed the whole thing, I keep seeing him from time to time but idk if I’m doing good, I feel this is too wierd and I’m ashamed
