Re: girls and guys
I wouldn’t be bothered by the porn bit, assuming it didn’t interfere with his everyday life. I think, by now, most guys know that porn is artificial, contrived and not real life. Personally, I would be more bothered if I found out that my husband was fantasising about his colleague, the neighbour, or some other close, real life, acquaintance than some random porn star he’ll never meet.
About this:
I don’t think whether or not a guy cheats is determined by porn. If a guy is a cheater and has the intention to cheat, he is going to cheat, porn or no porn.
