I met a glamour/page 3 girl who advertises on purpleport and have been seeing her on and off for 4-5 years now as an escort. As far as I know, it's only me and one other guy she sees in that capacity though, everyone else is purely for photography, and she is not local to you.
So basically yes, you may get lucky, better to do a nude/glamour shoot first and see if you click, then enquire politely about further possibilities
