There is the additional issue where you have, through repeated visits, developed a rapport with the masseuse to the point where your additional services go well beyond what would normally be on offer to the occasional visitor ( when the "I don't do this with everyone " line is actually true)
If you mention, in a review, that ( for example) you had FS with a masseuse when, as far as reports from other punters go, she only goes as far as ( say) B2B,then as sure as eggs is eggs, some randy punter will steam in and demand sex "because I read on the Internet that you do it".
