DFK, DATY and BBBJ screening tools I use. If those services are not offered, I don't book. IOP is subjective so I check that one out for myself. If that measures up, I will be back. Price point for me usually correlates with provider looks.
I'm a big fan of kissing. Always have been, as anyone who has read any of my reviews will discover. Sensual kissing heightens the feeling of intimacy, increases the level of pleasure when combined with other activities, and just plain feels good, especially when one's partner is particularly skilled. And there are some very skilled providers, as I have found to my ultimate enjoyment.
