So I learned a new word - masturbatrix. Essentially it is a dominatrix e that uses long tease and denial sessions using only a hj for release. Anybody feel free to correct me.
I have no appreciation for the very submissive aspects that I have seen in my research but do like the idea of an extended T&D hj session. That would be lots of fun. Especially if coupled with some prostate or strap-on. The number of varieties seems almost endless.
