When u either have sex for over three hours before you have an orgasm or have sex so long that you have an out of body experience like in Avatar.
Dude, while I was getting bored watching Avatar, my girlfriend gave me a hand job, then gave me a blow job, then I fucked her before I finally had an avatargasm.
