i have been slacking on my gooning lately and have been cumming 45 minutes to 60 minutes in. i want to go for at least 2 or 3 hours a time. anything i can physically do to resist cumming ? specific techniques

yes, squeezing the bottom of the shaft right above the balls will stop cum from shooting out. you still feel a nice orgasm too, but the nice load stays in.

I hear retro-ejaculation is unhealthy...

The man is correct. Retrograde ejacuation -- the condition of semen backing up into your body -- is not healthy. I don't know of any such mechanical impedant to cumming. And I'm not sure I'd try one if I did.

dont shoot your cum lol

does that help??

According to the Mayo Clinic it is not harmful......

I can edge up to 10 hours, which is my record. It takes self control, and a lot of it.

exactly this

this is good too. best thing about practicing edging, if you go too far and go over the edge you get to cum.....and start all over again

I'm currently taking Sertraline (an SSRI), which has made edging difficult. Long masturbation sessions are still very pleasurable, though. I just can't surf on the edge like I used to, unless I have many hours to devote. In a year or two, I plan on tapering off (with a doctor's guidance, of course).

But, it has forced me to pay more attention to my entire body. I spend more time playing with my balls, massaging my perineum, stroking my thighs and chest. Plus I'll switch up how I grip my dick, play with the head and frenum... Plus I'm more conscious of my breathing.

I find it easier to Edge if I am standing -- and when I think I am going to cum I stop TOUCHING and turn of the camera so I can't SEE anything that might put me over the edge :-)
