First , how do you see your camping sessions? 10 mn with max pressure? Do you stay erect ? etc..
It may simply have to do with mood and how easily erect I get. If I’m sexually bored it is very hard to edge period, the clamp helps but doesn’t always cure the problem. Also the body may react more positively to the clamping hand as opposed to a clamp.
I reckon it is is damn convenient for girth work: erect bends, jelqs etc..
I may still prefer squeezes (at least 2-3 mn holds) followed by jelqs to hit my penis hard, the only downside is they tire the hands a lot.
I’m pretty sure there’s more expansion with my hands compared to the clamp, on the other hand I hold them for less, on the third hand I have much less chances to have lymph fluid build up.
Of course if you come across drilla9’s thread you start drooling and want to focus on clamping only. Damn off I am to check it again, I don’t remember he described in details how he clamped, he sure gave some tips but if I remember right, no more.
I’ve come to the point where I’m convinced it doesn’t change squats to mix clamping, clamped edging, manual squeezes, jelqs, bends and do either of them as I please. I can get plenty of intensity out of them all, if one doesn’t go well I switch to the other. Consistency and what happens during each session is what matters most.
