Hey Valentino, welcome to Thunder’s.
Try using a plastic bottle that’s long and wide enough to put your dick inside. Fill it up with hot water(hot enough to bear). Be sure you don’t fill it up all the way, because your dick will displace the water, overflowing it. Use your judgement. Once your unit is inside, you can squeeze the bottle some to create a slight ‘vacuum’ effect so the bottle suctions to your skin allowing the bottle to stay firmer in place, if you wish. Not only that but, the vacuum also expands your dick, creating a larger surface area to be heated. Works great for me!
That makes allot of sense to me, and that’s what I believe I have been looking for, Thanks!.
One question though, do you mean insert the penis at the stage between erect and flaccid or just flaccid?
I’m in need of some serious guidance with prolonging my stretching, has anyone got a technique that allows them to hold the stretch for longer than 30 seconds?
