Is it normal to read criagslist personal ads?

I'm in a long term, stable, happy relationship and recently I got a craigslist app and have been reading the "Casual Encounters" ads. I find it fascinating the double lives some people seem to lead. I would never consider cheating, so that's not why I'm reading these. I just do it for the entertainment value.

My husband knows I read them and I think he thinks it's weird lol, but he's not the jealous type and doesn't seem to mind. I wouldn't do it if he did.

Just wondering if it's normal to enjoy reading personal ads when you're happy in your relationship and not looking for anything?
