I've been having a lot of conversations about this with my friends, so I thought I'd take it to the forum and see what ya'll think. The title says it all. What do you considering cheating when you're in a relationship with someone? Obviously, when it comes to getting physical, most people consider sleeping with someone else as the most defined form of cheating. But what about before that? Kissing? Naked photos? Texting in a flirtatious or suggestive way? What about emotionally cheating? If your significant other was engaged in sexual roleplay online with someone they've never met (nor someone they've ever talked to about meeting), would you consider that cheating emotionally? What if they were just browsing for a pen pal but hadn't actually made a move yet. Would that be something you'd be upset by? And what about images? Obviously pornography comes to mind. I've met my fair share of people who go either way -- porn is okay, porn is terrible. But is that just for videos, or do photos qualify as well? What if your significant other had naked photos of someone they knew emailed to them, images that they promptly saved for future viewing? If they were just topless photos, would you be upset? What about below the belt images? Does that cross a line? This is obviously assuming that everything done or viewed was during your relationship -- including receiving or viewing any kind of image (whether it be pornography or naked photos of a friend). What do you think is the line when it comes to cheating, and when is that line crossed?
