I think its okay as long as it doesnt ruin your sex life. My wife and i are still pretty active. But if she leaves me in the house alone for a few hours i might watch scenes and collect photos for a few hours. I probably only get off once or twice during this though.
Im into a whole lotta stuff. I like amateur a lot too. The only stuff im not into is bondage/*********** stuff bathroom stuff, and gay, those just arent my thing.
