Some girls offer bareback but not unprotected sex, or unprotected sex but not bareback. I think a lot of pimps of foreign girls just tick bareback without the girls knowing anything about it. It must be rather frustrating for actual bareback-seekers trying to find someone who really does offer it!
Then there are those who tick "pregnant" while offering various unhygienic services, and apparently not actually being pregnant. Those who are genuinely pregnant always make a big deal of it, showing pics of the bump and a running commentary about what stage they're at. I assume that if a "pregnant" girl doesn't do this, nothing else on her list can be trusted, and I will look elsewhere.
