I can not believe that no one is currently interested in playing with hot wax at the NYBC. Since I moved out of the area I have not been able to attend frequently, but the last time that I was there which was in August of 2017 there was indeed hot wax play. Byran and especially Phen who run the club are into such a scene.
Of course, in recent years the club has morphed into something different from its BDSM origins with many guys attendeing to “get lucky” to phrase things in a diplomatic manner in what is a public forum as opposed to having S&M type activities. Hence, I can understand that on a given night many guys who attend might not be into wax or even flogging etc. However, Phen definitely is an expert at wax (and so many other things) so ask any you just might get your wish.
