That gives the skin (well, the "mucous membrane") the best chance to re-bond to the underlying tissue.Also, an itching or tingling sensation is usually an indicator that you don’t have a blister yet, but it’s ringing the doorbell. Fuck the rest of the session; stop immediately.
Further also, once you’ve had blisters, new blisters tend to form over the same spots as old ones. I suspect that’s because the bond between layers has been weakened. I have a spot to the left of the meatus isn’t visible until I hang for about an hour; after that, I’ll see a lighter-colored patch there. It’s not a blister, at least not yet, and it doesn’t seem to hurt anything, and goes away in an hour or two.
It makes complete sense man. However, in my case is different. Due to the same reason you’re stating. That same spot for me became so chronic, that every time I get a blister is a bloody one. Is not the smooth water bubble, is a blood bubble. So once I feel the first symptom, is already too late. Currently my session either succeed or fail. If it fail is not because I stopped it, is because with the blood and fluid buildup the whole cup slide out.And like I said, once I feel the blister theres no point in even stopping because is too late.
