Sounds like your a real pro.Tend to be a once a day kinda guy. Maybe twice, maybe miss a day.... let it rest up a bit.
Duration? From a 5 or 10 minute wank to an hour or maybe two, edging a while.
Myself I find if I jack "too much" it just gets chaffed and sore, and is less fun after. So yeah, I use
some spit, or lube, my pre-cum... and try not to over do it )
