Hi ML,
Welcome to SAAFE.
I have been sitting trying to think of a nice polite way to say it, but the easiest way I can put it is, you can buy all the domme tools in the world but that won't make you a domme. Being a domme takes a lot more than that. A domme booking also takes a lot more out of you than a vanilla or GFE one does. Both mentally and physically. Pardon my expression but most people know how to shag, not everyone knows how to domme.
I would suggest you start out with doing "normal" escorting and break yourself in for if you suffer from anxiety and social awkwardness you are going to find it extremely difficult to get started. It takes 100% effort to get started as a normal prossie but being a domme takes a lot more. It is not for the faint hearted.
I would suggest starting in straight prossie work and in your quieter spells and read up A LOT about domming before you even think about starting. If you try and start out any other way it may have adverse effect on your business if you fail to come up to par. Domming is not just about "ordering guys about", there are too many different aspects to go into on a forum but one suggestion would be to look at some other girls profiles on AW who do do domme and are quite established with it. I don't mean pick a female with the word "mistress" or "madam" or similar name for anyone can do that, but it takes a lot more for someone to become a real domme.
When you are building your business up and reading up about domme work it will come to you how you will want to start a session, each person has their own way and domme is different from vanilla or GFE.
When it comes to location ie Incalls or outcalls, due to the nature of the beast and the equipment that is required to the sessions, most dommes only do Incalls. Can you imagine carrying half of the stuff you say you have purchased to a hotel outcall, not really viable.
Take your time getting started and blend yourself in gently, escorting is a big step to take without jumping in feet first with something you really know nothing about, especially if you have a nervous personality.
TC and all the best.
