I do a form of this. If I like an actress I will look up their wiki and read about what her life was like. I don't look up nudes - I don't think you can find them anyway. Well, fake ones, sure.

Not sure if it's a problem - my wife doesn't seem to mind. I will relate interesting tidbits with her, like Hmm this gal married her leading man from (whatever) movie (told you those scenes were pretty hot!) Or wow, she was raised in Budapest and plays violin. I think it's because I have an intense curiosity. I mean, I look up everything. To people like me, the internet is a godsend.

To be totally honest, I would never cheat on my wife; there is no sexual interest (like they would look at me twice yeah right). It's more like, I'm in awe. I'm in complete awe of their beauty. Sometimes transfixed. Maybe that's the deal with your husband. I don't think it's possible for me to ever stop looking at women.
