When you're having sex while playing games with your boyfriend/girlfriend.
Does not matter who or what you're fighting - if your other half wants to have sex and play games, you're having game sex.

During the act, you're free to change styles but you must keep having sex until you're done playing.
Me: Dude, what the hell happened? You just disappeared from Skype last night!
Friend: Me and my wife had game sex while fighting the final boss.
Me: ...What in the actual fuck?
