(All comments based upon the ladies I see being in the $500-$800 per hour range. Some I continue to see often, and others I would have liked to but don't because of the below.)
1. Hygiene: 3 major areas that, if she falls short, I will not see again. First, keep your kitty, and the lingerie you put on it, CLEAN. Ladies, ladies, ladies, you don't think you smell 'off' because you are used to the smell. It takes more than a babywipe to 'become fresh'. Unless you have a line out the door, it doesn't take much showering to make yourself fresh. Once you do that, also put on a fresh pair of panties. Not the ones you had on when the last guy was there and he made you wet. Your wetness on cloth is a breeding ground. Even if you only do wash once a week, having 20 pairs of panties/G-strings takes up so very little space.
Second for hygiene, please leave enough time in your weekly schedule that you can eliminate nasty stubble around your kitty. If you are going to allow DATY, having stubble down there increases the chance of you, and him, picking something up from the other. If flossing is to be avoided to avoid micro cuts, what do you think is happening to a guy's tongue with vigorous licking that can happen with DATY?
Third for hygiene, avoid odiferous foods an hour or two prior to a date showing up. Really crimps the desire for DFK when you taste like lunch.
2. Connection - Use the name I gave you in screening emails, during the date, and mention some things from the emails we shared ahead of time. It shows interest (even if fake). Shows you spent a few moments thinking about me before I showed up. If doing an incall, show me where to put my stuff, where you would like us to sit, etc. As we do the initial chat, stay close and use your hands in a caring manner (touch my leg, hang up clothes I take of, etc.) And once I cum, don't act like a switch is thrown and become all business-like. The best ladies keep a consistent demeanor during the date. Finally, if you'd really like to see me again, send me a 'hey I had a great time' email within 24 hours afterwards. In it mention something specific about the date or things we chatted about, not just a "Hey baby, I had an awesome time" cookie-cutter line. My ATF's have mastered this Courtesan behavior and get repeat business from me.
3. Atmosphere - Have enough light on so that I can see my way around, and see you. If you have a two-room hotel suite or apartment, have the first room be brighter. Save the candles for the bedroom area. Make sure the bathroom vanity area is orderly. Have a fresh soap and towel all ready for me. Added plus, that always, for me, has led to a future return visit, is coming into the bathroom as I shower (let me know you've come in) and offer to soap my back. Very erotic. (Again not something a "line-em up at the door" woman will want to do for obvious reasons, but if you advertise as a 1 or 2 guy a day type, figure out a way to make this work.)
For the above, I have found the below age 30 ladies to be less aware/less concerned with these things.
Ladies looking to always improve their encounters are becoming more rare in this industry. Each one of the above by themselves may not keep a guy away, but added up, it reduces the chance for a return in the long run. I've seen a number of ladies resort to the perpetual 'new special' to entice return visits. The irony is that when all the little things are done well, the need for 'specials' become rare.
