I did do it - ever since I got my first internet connection in '96. I stopped about 1 year ago. Wife was starting to have problems with it. I had a rather large and extensive catalog of pics and clips organized very precisely on my hd. I'm not sure why all-of-a-sudden it started to bother her, as I had been doing it for years, and had a playboy subscription for a while; but out of respect for her feeling, I deleted it all and stopped hunting for it. She never told me or asked me to stop, just that it was bothering her and making her feel bad.
Now, I don't go out of my way to NOT look at it, like if a pic or link is posted to a forum or newsgroup. I just don't go on surfing sprees, downloading and saving it. I can't say that I really *miss* it..
We do occasionally watch a pr0n movie together sometimes, but that's about it.
