Yeah, 99.9% 'gasm, with total loss of control. You've never been out of it until you've been out of it from gooning.
I've gooned from been fucked in the arse, rimmed, from fucking and from wanking. A lot of sites just talk about gooning in relation to wanking, though so I'll talk about that.
I can't just start beating my meat and suddenly start gooning. I need a build up. With wanking it's only happened from edging, when I've got a few cycles into it. For me there's a transition state that nobody else seems to talk about I don't know if that is unique to me. It's a semi trance state and is really fucking mind clearing. It's like I'm consumed by the need to keep the wank rhythm going. Afterwards even if I haven't hit goon it feels like I've had really good meditation or therapy or good shit like that.
From there I slip into full on raging, hollering gooning out. I reckon my typical orgasm lasts about 30 secs and my goons last between 2 and 5 minutes, until I tip over whatever tiny edge is still left and I spurt my load, leaving me fucking wiped out. Some lads can be in this gooning state for hours before they cum, those bastards are my heroes!
I've probably only gooned successfully 7 or 8 times in my life. It's hot but elusive. Everyone needs to experience it though.
