In my experience, the math does not support the idea
[QUOTE=MrEnternational;2724208]Keep telling you that it is something that is just done, not something that is negotiated. And you have explained your reason for negotiating it before. But not once have I told a chick that I wanted that but it always happens. Actually I have never told them that I want anything in particular and stuff just happens. The extent of my negotiation is only on the price and I have not been disappointed yet. YMMV though I guess.[/QUOTE]Yes, I still do the "go with the flow" thing every now and then and used to do it a lot here years ago.
Over the past 10 years my general success rate for it "just happening" with the girls I choose runs at about 25% in Bangkok and 0% in Pattaya. That is way too low a success rate to be paying money for what will then turn out to be a likely middling BBBJCIM at best and no sex at all at worst. The math simply does not support the idea. So I negotiate upfront the vast majority of the time.
But I did get a ton of impressive Safety First lectures before they left. Even from some of those 25% success rate girls in Bangkok right before they grudgingly agreed to bareback for more money.
Which, of course, I always find to be highly erotic and stimulating foreplay and not the least bit of a buzzkill.
Uh. Joke.
