Being someone who used to date and live with a Courtesan for over 7 years, I'll say go for it and tell your potential partner in the beginning before both sides got too emotionally involved. If he was good with it like I was(after a lot of sleepless nights and soul searching and decided that my love for her was deeper than her line of work), then it will turn out to be a great relationship. We still talked about our work days but not in details about the clients or what they did. It was more on personal safety and emotional support. It sounds easy for this line of work but in fact, it is the opposite because not every client is a nice gentleman. As a partner, you also need to make her feel comfortable enough to express her feeling and frustration. Intimacy was excellent and the most important thing is for both to agree on a particular service that she will never provide to a client but just her partner. Be it a DFK or whatever else... because that will give you the feeling and also reinforce the emotional security that there is still something reserved just for her and you and instead of sharing everything at work. In my experience, I found that a SP SO is way more loyal in a relationship (100% monogamous outside of work) than normal women. Because she already had her fills of men at work and there is no need to have an affair or what not.
