I just need to get this off my chest, I still have sexual fantasies about being with older guys.

I just need to get this off my chest, it’s been awhile since I’ve really been in a spot where this is a problem, not that it is a problem. In the past I was involved with older guys, I had all these kinky thoughts and I don’t really know, I drank a lot and slept with older guys and I loved it. I stopped over a year ago, I’ve been in a healthy relationship for a few months now and things are going well but the thought of being with older is creeping back into my mind, none of my current friends actually know about any of that and I wouldn’t do anything behind my partners back, I just can’t seem to let go of the fantasies?? I don’t have anybody to talk to about these things, my partner hasn’t ever been that kinky until we’ve explored together and my last couple of friends I’m just not sure if this is a topic I can bring to them yet.
