I think you both have not found the right girl from the beginning. I see my favorite girls often and always tip the same amount. I don't play mind game with them, and each encounter gets more passionate than the previous session. One has to treat each session with the same vigor as you expect from them. The more you satisfy them the better they will return the favor. Keep experimenting with new ways of pleasing them and they will do the same. I can't wait for my next visit.
1. Some girls are into playing it like a relationship. Other girls are much more interested in getting the most money each time. For these girls, knowing what things they can do to get more of your money, gives me better sex. period. I've seen it over and over. If she knows that she's going to get an extra 20 or 40 and all she has to do a little extra rimming, or make sure you blow on her face, she'll deliver every time. if you havent communicated that its much more what shes in the mood to do. SHe's not my girlfriend, I'm paying.
2. There are other girls that take a long term view, and really enjoy your company, and those girls are certainly keepers. I have a couple of them where the relationship is still going on and is over 5 years long, one about 10. Those are different.
3. I do a lot of 4 hands. like 1-2 a week. that's an exponential increase in the factors you have to consider in motivation, tipping and outcomes. I bring this up because thats where i first started having to do this experimentation with differentiating tips, and delivering direct messages about my happiness with her performance.
