I think it depends on how you look at it. I knew a guy (wont name names). He was married to a beautiful young lady, well they never had sex as in a mean the sex stoped at 2 months of being married. He was addicted to porn, he said he relized later after much therapy that there was a emotional conection to the porn in some wierd strange way, so I guess in some cases you could emotionally cheating with it. Wierd I know but I see no harm in it as long as you guys are still having regular sex an porn doesnt have an effect on you realtionships. I could care less if my husbnad looks at porn as long as im getting mine regualarly lol , for me it doestn do any thing i need to have the contact with another person.
Cool. Every relationship is different, every person is different. Some people think that a married man having sex with someone other than his wife is cheating, some don't. Every marriage has their own set of rules, things that are unacceptable or deal breakers.
Of course this post will likely have the replies: "At least he isn't cheating" and "Every man does it." I say, why does a woman have to pick between 2 things that hurt her? Would you rather have a broken arm or leg? Neither would be the most common sense answer. And of course not every single man on the planet watches pornography. I'm not big on making sexist blanket statements.
