Any one else thinking of when they might have had intrusive thoughts but did not react to them?

Like I was roleplaying with characters online and I got the idea the mother should do this with her young son. Never did anything but the thought came and went.

Now I am reflecting on it and why it is bothering me now.

I have very little anxiety but it still bothers me. I don't want the thoughts. I find myself checking and reviewing my memories. I can't tell what is false or real. And thinking maybe I did try and act it out in the roleplay but caught myself and wondered why I wrote that stuff and quickly changed it. Seeing as I have a tendency to write what just appears in my mind.

It is why I can't listen to music while I type because I end up typing the lyrics.

I had these similar things happen when I was having my HOCD. I tell myself that. Not noticing my old attractions and such. Can't tell myself this or that of how it was before the obsession. But does not help.
