Ms tnt and I always used heat. We have a towel warmer in out rest room and it heats towels very fast. The nice thing
about the towel warmer was that it warm 6 large towels at a time or 12 medium towels or many small towels. So we were
constantly rotating warm towels in between sets and during the sets I would wrap the base and balls with the towel which was
still very warm while ms tnt did the ulis, edging and pulling on my unit. Some say heat doesn’t matter, but I am a believer, hell
I gained over an inch in length and over .5 inch in girth in just under a year. I believe the heat attributed to those gains, by the
way, towel heaters are not that expensive.
