Quite a number offer BBFS
Back before the mid 80's, BBFS was common on the menu among the MP's and Incalls. I have a female cousin who worked at that time and she said that the girls all did it.
Quite a number offer BBFS today - there's that latin girl in New West, another lady in New West, Cindy the little asian SW, Sara at Lougheed Mall, who can't be named at Bex but no longer there, a couple others at Bex, some at that Seoul place.... etc. I've even been personally offered recently a few times over the last couple of years. And way back when I started in the late 80's, I did it 2X. Boy was I ever naive. I got all my tests done, especially HIV, and was lucky I never caught anything but chlamydia from a g/f I was with for 9 months! That's all over now and its nothing but covered with SP's!
