In previous threads on [words=http://www.mattersofsize.com/join-now.html]MOS[/words] as well as PEGym, there's been plenty of talk of heating your junk while doing PE to create faster/permanent deformation where the temperature usually touted to effectively deform tissue was at around 104-112 degF (I can't remember the exact numbers). I don't believe that one could reach those temperatures in their members due to the zeroth law of thermodynamics, but! If one were to heat your entire body to the same temp then its only natural that your member would also reach that temp. That's why I wonder if anyone has done PE in a sauna. The temps reached in a wet sauna approach 114 degF, which should be a sufficient constant heat source to allow for permanent deformation.
