now this is just me guessing here.
I dont necessarily think that because they have BB listed on their likes list that they actually offer this service.
not even sure how many of these girls that fill in the profiles themselves, I think its more like ticking as many boxes and negotiate from there.
I dont do BB but I always ask beforehand if they offer anal and watersports - even if it's listed on their profiles as being offered, I have found that many dont do it. in a few instances, I have been and then told that its not on offer.
so for me unless its written in the text on their profile that BB is offered or sometimes when they reply to messages, they advise that BB is on offer,
so I wouldn't take it for granted that they offer bb, if in doubt then ask - whats the worst that could happen
but in any case - if they offer BB as per above - then I wouldn't visit or contact
