We always try to compartmentalize and label everything, when the reality is that all of life is on a continuum. What is true for one person, is not for the next.
I would say that if you feel as though you are not in control of seeing companions, then you have a problem. If you feel powerless to stop, or feel compelled (beyond a normal desire).
Ask yourself honestly if you would be able to stop if there was a reason to (ie creating a financial strain, constant preoccupation, interfering with your work, family life, social life, and other activities which are important to you etc.)
Also, if is creating any negative feelings for you (shame, guilt etc.) and you continue, it is probably an indication that you aren't as in control of the situation as you should be - or you would have stopped.
If it is just something you are enjoying, and perhaps becoming a little indulgent in (without causing strain or hardship to other areas of your life) then you are probably good to just relax and have fun with it! We all go through phases of indulgence or over indulgence from time to time, and you have just chosen ladies as your source of pampering rather than food, shopping, exercise, substances use, spa appointments etc.
