I am the original poster of this inquiry. Thanks particularly to Consuelo, whose reply was sufficient for my curiosity. There seems to be no word that is specific to the deer-velvet-rubbing. I now leave this subject to those of you who are rubbing your conscious itches.
PS: In general reply to numerous private messages I have rec'd: Thank you for your kind words; I enjoy Latin, Swing, and Smooth dancing as a hobby; and I am heterosexual.
