How important is heat while doing PE?
You can go an entire
successful PE career without ever using heat for warmups or warmdowns. It's not necessary, but technically it should be
better.
Some swear by it. I find when I use heat my penis is more "stretchy" after
There was some study posted here in around 2009 (iirc) (I think by me for that matter) of a study which had found that the body's collagens become the most pliable when heated up to a temp between 104*F and 115*F, so yeah your feeling stretchier after adding heat is good science.
If it
only made you stretchier, it could make achieving gains
more difficult .. because something stretchy that has not been broken down or affected by the stretching forces would have no reason to remodel (and grow larger). And there is probably
some of that going on. But, on whole, the way that heat makes the tissues more susceptible to breakdown (and later on then, remodeling) by the PE exercises should make it better than not using heat/warmups.
Other elements of stretching the particular collagens of the penis is that they will
try to resist stretching in length directions (pulling out, like a 'North/South' vector), and resist stretching in width directions (ala girth, being stretched laterally, like a 'East/West' direction) , which is every
obvious direction that PE tries to modify.
Using a lot of force that is great enough to overcome the resistance is one way to overcome that (if the tissues don't respond by becoming tougher and more resistant)... but there are two types of better ways to go about it ..
The collagens of the penis are not as resistant to stretching in Diagonal directions, and they are not as resistant to stretching in deflected directions. This is why exercises such as Bundled Stretches, and Jelqs/Slow Squash Jelqs, and Cranks/Directional Pulls (and anything else that uses diagonal or deflected forces) work especially well.
To add all of those tweaks together, the fastest way to make gains should be to heat up between 104 and 115, and then use diagonal and deflected vector exercises .. at least as
pre-fatigue exercises (breaking down the resistance) .. before doing additional exercises of other types.
