If I may presume... I don't think Ozme52 was saying that people golf and fish to get away from their loved ones. I think he was saying that when you said it was cheating if you spent time and energy away from your loved one(s), that was a rather broad definition. Work is spending time and energy away from loved ones. When I am online, I am not spending time with my husband. When I'm at school, I'm not spending time with my husband. When I'm with friends, when I'm doing things for me, when I'm doing a lot of things, I spend time away from him. Does that mean I'm cheating? By your definition, yes. But to me, that's how life keeps me healthy. I am not less close to him because of the things I do. I do not love him less for the time I am away, and he doesn't love me less for the time he is away, either. I think we'd be pretty sick of each other if we focused all of our energy on one another all the time, every day, with no interruption at all. (Sure, we'd get creative and it'd take a while, but still...)
That being said, I still respectfully disagree with the stance that cyber/phone sex is not cheating when it's hidden from the rest of the partnership. Masturbation is one thing. Masturbating with another woman? There'd be some white-hot rage from me. It's about moving that fantasy into reality. If he sees strippers, he's not masturbating with them. They're there for money. He's there to look. But once a personal connection is made... that's betrayal. In my relationship, anyway. I liken looking at porn online to watching strippers, and having cyber/phone sex to hiring a hooker, or worse.
