I think the same... i try don't expect that any guest that appear on VH (of course that there are some houses where a new guest may easily mean sex will happen ) will have sex or be nude... to don't create high 'expectations'... She may be only friend of one of he girls that is shy enough to don't be comfortable with online nudity... If she shows (and already give us a quick peek of the boobs) better
Not always.. most part of the time witch is normal, since it's the boyfriend... And maybe don't want he to be 'official' because that will mean that the 'cake' will be splitted by three
