In my 7+ years of going to clubs, I only had one CF/ATF that I went to see regularly for a while. It was around this time last year that I met her. I continued to go see her in the club about once a month. The first 5 visits were great. Then things plateued. She was doing everything she could do without breaking the club's rules. I wanted something from her I knew I wasn't going to get, so I tried a few other clubs and the girls in these clubs gave me exactly what I wanted from her, and on a few occasions, I did not have to spend as much as I was spending on her. I still liked her enough to go back to her club and see her, but I suddenly noticed her approach being more business like and I no longer enjoyed going to see her despite the fact she still gave great dances.
Before I met my ATF, my club visits are very much like Papi's. I would spread my money out among several girls and not apply the favorite label to any particular dancer. At a few clubs, there were girls that gave great dances and therefore I would always get a few dances with them, but it never got to the point where I would spend the majority of my money on them.
But since my experience of spending a ton of money on one girl led to me going to extras clubs and indulging in extras, my approach is now to get the best of both worlds. If I am going to spend hundreds of dollars on one girl during a club visit, I better be getting extras from her. Otherwise, I will just get a few dances with several girls.
