It is well documented in the literature that temp above 39C causes collagen fibers and fibrils to contract, absent any applied stress to counter that tendency. So heating the penis above 39C without load will contract, reorganize, and resolidify the collagen in a shortened state once the heat source is removed. The higher the temp gets, the worse this effect is; almost imperceptible at 39C and then amplifying convexly with each 1 degree marginal increase in temp.
To prove this to yourself, go throw a low-fat hamburger patty or bratwurst on the grill and watch the dimensional changes. IOW, heat isn’t either beneficial or detrimental, it is transformative for better or worse depending on what you are trying to accomplish. It simply assists bonds to release and then reform between both the fibers and fibrils.
If you have a patellar tendon that keeps dislocating, then placing the knee in an unloaded position, heating the tendons to 43-45C, and then allowing them to cool without stress is appropriate. Doing this repeatedly and otherwise while cool using the joint through about an 80% range of motion, will over time tighten that tendon as long as you don’t re-strain it within 9-12 months.
In our case, we have the opposite goal. Use heat to facilitate fiber and fibril sliding in an elongated direction. So the penis should never see temp above 39C without load applied.
