If BBFS is a forbidden pleasure, it must have made Inglewood CA (where the Lakers used to play), circa 1995, the Forbidden City.
There's no contradiction, the girls who offered me BBFS was as a perk. This was in the late 80s and early 90s, when sex was a lot safer than it is today. Ir sounded like the girl in OP's thread was shooting an angle. Two completely different scenarios.
Twenty years ago, you got the clap, you got a shot of penacillin. We've since moved over from Cipro to Rocephin, which is a testament on how hardy the gonococcus bug has become.
In my situation, disease was a longshot, pregnancy was impossible and their offer had nothing to do with romance, as the girls involved were career professionals. In the OP's situation, well, that one he might have to sort out. She obviously likes him, but if she is playing him, only he can figure that one out for himself.
I have less of a problem with it than other bros here, because I'm very much aware of the realities of this hobby, and how it intertwines with m/f relations. I have no S/O to go home to, so, what's the big deal?
But...I'm not reckless about it. Doing BBFS in, say, a 3W country where delivery of medical services is poor as well as sex education, that would be stupid. It would be crazy to do BBFS in say, TH or PI (for different reasons). My situation was with girls who have been doing this for years, will be doing it for another 15-20 years (maybe even longer with a crack plastic surgeon), in the US of A.
