TLDR: As a happily married man, I don’t think you should worry but I do think you should create your own fantasies w your husband.

My wife is curvy and fine as hell, we have great sex 3-4x a week and I watch many different types of porn. Some old some young, some curvy some fit, and in all sorts of combinations.

I’ll even watch porn and masturbate during the day about one thing and then have incredibly amazing, intimate sex at night w my SO. They are completely unrelated and I don’t think at all about porn when I’m w my SO.

Someone once told me that sexuality w yourself and w your partner are like candles in a room, they don’t take away from each other, they both increase brightness of the room.
