estatic,
The Thermotex Platinum (3 pad model) is rated at 36watts.
Renholder,
Let me start by saying that I don’t PE that much, as I spend most of my PE time researching how to effectively do what we are trying to do, and nobody has effectively demonstrated that yet - only that ‘certain things sort of get results for most people some of the time’.
Here’s what I do currently do (as of the last month or so):
Once per week (occasionally twice) I use either a cable clamp or a velcro strap at the base of the penis to restrict blood flow by about 50%. I apply the IR pad and leave it until I get the penis to temperature. The correct temperature to me is a certain fuzzy sensation that is comfortably warm with a very deep heat sensation (no skin scalding at all). Depending on the clamping degree this can be anywhere between 10 and 30 mins. I aim for it to take 30 mins as it seems to have a healthy pink glow that way, whereas if I do it quicker it gets a very deep oxygen starved look about it.
I remove the pad and restriction, and using a soft cloth to aid grip, I stretch hard for as long as I can maintain the grasp, and re-grasp as needed if it slips. I stretch it in all directions, then U bend stretches along the full length of the shaft in multiple directions to isolate areas individually. The exercise portion is no more than 3 mins. That’s it.
I measure the FSL and hope to see about 1/16 extra. If I do I’ll repeat mid week. If it seems less then I’ll wait a full week. If and when I don’t see any improvement then I’ll wait longer still. This seems to be working for the moment, but I know from past heat based extensibility experiments that there comes a time where you just have to back off and let the body do it’s thing to normalise around this new set point before any new gains can occur.
If I was doing the same thing with girth then I’d use clamped squeezes instead, but make the exercise duration maybe an hour or more and apply heat the whole time, and release the pressure every 5 mins or so (heat and clamping seems to burn oxygen at an accelerated rate).
I have two vaccum tubes, but use them very infrequently just for the sake of mixing things up or boredom. I don’t consider them as part of my PE program. Using a pump is a good way of stopping the blood cirulation in itself due to the pressure it exerts on the pubic bone (greater pressure on the tube than pull on the penis since the area of the tube is greater than the penis inside it), so a constriction device isn’t really necessary.
