the question of bareback may seem counterintuitive at times. Theoretically, if a girl is not charging extra, she is free to INVITE only those she feels safe with to partake. However, if a girl is advertising BBFS, she has a harder time saying "no" to a guy who booked her expecting BBFS regardless of the fact that he may have a wart on his dick or is hung like a stallion. For the girls that don't charge extra, the model really doesn't work to their advantage unless they can stay UTR like they did 8-10 years ago. Bareback was never mentioned in reviews nor discussed on the boards, and the system worked well for everyone.
Many of the girls who are NOW GFE only used to offer BBFS UTR to a limited number of their regulars, usually guys coming two or more hours a week, either in one session or two. Once someone outs her, then EVERYONE is pressuring her to give it up and her work is no fun anymore. Some of the top-tier girls who left LA got tired of having every swinging dick who walked through the door asking for bareback. This is a good example of killing the goose that lays the golden eggs. Not everyone gets a golden egg, but without the goose, NOBODY gets one. A few guys who can't keep their mouths shut and betray a girl who has trusted them to keep their mutual BBFS activities a secret end up ruining the deal for everyone, including themselves. Usually, it's the younger, insecure guys who want to brag that they are getting BBFS from an UTR girl. Kgirls who advertise GFE only absolutely HATE guys asking for bareback. However, if you keep your mouth shut and become a regular, she still might offer it at some point.
To answer your question, generally speaking, BBFS girls who advertise are rarely ever comparable to the top-tier girls that are GFE only. The girls that are not as pretty or skilled who advertise bareback KNOW that you are seeing them because you can fuck them bare, not because they are such great providers, so they have no incentive to give you a 100% effort. If yon read a few hundred reviews of BBFS Kgirls, you will notice that the reviews often show average or below-average service, save for the fact that they did not have to wear a cover. Yet, younger guys continue to flock to them JUST because they can get BBFS. Always remember that allowing BBFS requires no special skills in the way of BBBJ or any other activities. You are paying strictly for the right to remove the cover. Unfortunately, that is how the sellers of BBFS view the Buyers. That's why so many mongers whine about the service in their reviews. There are always outliers that do their best no matter what, but these are mostly those who also have issues in the Looks category. They do what they have to in order to compete with the top girls.
