There is no place to learn to be a professional Domme other than by finding one who is willing to take you on as an apprentice. Certainly no formal training and I think many just practise in lifestyle before deciding to go pro. As denuseri says, you do need to be careful as there are a lot of bad dommes out there who take money for the services they offer so you need to make sure you find a good one.

A few hints for looking for a good one:

- Check her website and read the information there. Many of the better Dommes are also lifestylers, i.e. they do it for fun as well as profit. Means they are likely to also have a lot of interest in the scene and know the conventions and the rules and so on rather than being just a 'prostitute with a whip'
- Most decent Dommes also do not offer sex or any sexual service to the clients they serve and this will be posted on their website somewhere. Again,a nice clue that you are dealing with a good Domme rather than a prostitute or 'escort'.
- Read thier philosophy about domination in their 'about myself' section of the web page and see if you agree/disagree with their opinions about the lifestyle. Again, most professionals have one of these and it makes sense to work for one who agrees with your own ideas.

If you tell us where you live, it is possible someone here may be able to tell you about Dommes local to you who may be willing to work with you - either talk to you about the profession or even give you some traiing/experience/supervision. I have some contacts in my local area and I would think others would in their's.

Also, a lot of self study is good - Adriana'a advice is especially useful I feel.
