I BF a girl out of the King's Castle in Patpong BKK that had a body as hot as any in the place. She was a dancer too, so I had a very thourough preview. She spoke English very well, and was pretty aggressive about going with me. She gave a good massage, and took care of business with great skill. After the fact she asked me to guess her age. Not being stupid, I declined. She told me she was "over" 40, and a grandmother. We then had a nice chat about our grandchildren. All in all, she was one of the nicest and best girl I met, so to speak, during that whole trip.
If the body is good, and you can't tell the age, what difference can it make. IMHO it can only result in better performace. I don't want a girl that I have to show the way. I prefer a lady that can lead me astray.
