I wish you luck with that. It took over 2 yrs of training from a full time Dominatrix on the East Coast until she cut me loose to be on my own.
You do realize that there's no sexual interaction whatsoever during those types of sessions correct? That reason alone will keep a lot of guys away because most men in the hobby do not truly understand the BDSM roles, especially that of a true Dominatrix.
Also, to be a Dominatrix it costs a lot of money to get all the different types of toys that are needed. I've spent well over 10K for my toys and a lot of toys need to be replace quite often.
The roles that you speak of are a little confusing as I've never had a Dominatrix refer to her as an amazon. Being a goddess is nothing more than body worshipping and the governess role is nothing more than taking on the role of a parent. But then again......a lot of people make up new terms all the time, but I'm old school and still use the terms of the past I guess.
If you want to talk about it, give me a call. There's way too much to type out.
