Never met any of the bath babes so I can only comment on what I've seen on t'internet.
I have seen them advertising parties fairly recently where Tiffany/Tasha was listed as being there with Annie & some others. Don't know if bareback was going on there but after seeing that advert along with threads on other forums it certainly put me off from seeing any of their girls.
Most of us take risks when seeing prossies, such as indulging in OWO & CIM, & I'm certainly happy to take that risk as the chances of catching something is relatively small, but I wouldn't want to risk seeing someone who happily parties with well known barebackers as you just don't know & isn't worth it IMO.
Granted, seeing anyone is a risk because they could be bareback fucking anyone & you wouldn't know either but I'd rather it was someone who doesn't blatantly advertise it as a service. Ignorance is bliss.
