IS THIS CONSIDERED PORN?

If you're leaving him then what does it matter now?

Not really porn but how bad its to be taken depends on the context he did it. Is he talking specifically to the girl dirty or more of a character ingame roleplay where its the character toon thats the attraction. Chatting up a personal sexual chat with other then your wife is fairly bad, but if its an ingame roleplay sort of thing and not actually directed at the person playing the character but the character ingame thats not so bad.

Will also add do you know the one in question is actually a gal (he's given a real name of her or heard her voice on voice chat?). 95% of online gamers are male and a large number play female characters and often not in a dirty way… simply if you have to look at the butt of a game character when playing would you rather it male or female? Generally males and females with that in mind pick female as the female form is considered universally more attractive from both sides.

If you are leaving him, then y are u asking us this?

For being dirty lying cheating sshole.
