Borovets has a number of fully naked lapdance clubs. They used to be quite blatant in their signage (to the extent that I overheard a lad of about 12 saying to his Mum " we'll meet at 12.30 by the titty bar".)
Despite the mafia-looking heavies on the door these guys are actually quite friendly.
Last time I was there, admittedly about 7 years ago, the strippers weren't adverse to touching, HJs and BJs discreetly in the club. More than a couple offered takeout services. Given the elapsed time, YMMV.
I did hear, however, that the outcall business is mafia controlled so take care .
