Thanks TNT, the question then becomes how well will the woman receive that advice without becoming defensive. Some women would be moritified hearing that, especially when this is their livelyhood. Since there is no physical sign saying what type of women they are, you would never know how they would react. Some may even become vindictive as a defense. I would dislike losing the hobby connection with someone we enjoy our time with. I would say 75% of all of my encounters are oral only, DATY/BBBJ, because we had a great conversation before we even started.
I would be willing to compromise on my requests. A lot women don't like washing their hair multiple times a day and I understand that repeating that ritual daily could get tiresome if not detrimental to the health of her hair. I'm lucky in that I live almost in the heart of hobby central (at least until I move next month) and can be at a private incall or the galleria within 15 minutes. If I had to drive longer than that, I'd feel obliged to ask for a shower before we started, especially in this heat.
Side story: I dated a shrink some time back and it was her that started that little cleanliness ritual of "shower before sex, shower after sex, change the sheets after sex..." Never date a shrink who's also obsessive compulsive, tedious to say the least...
