OP - may I ask if you see this strictly as a dinner date or are you open to the idea that it might lead further. If, for example, you edge your question about movies into the conversation and she replies that she prefers first hand experience over watching movies.
Are you hoping to review the food, ambience and quality of repartee or something more carnal?
I would have no interest if he bothered to take the time to report back here about such an experience, if she's a WG post a link, other members might be able to tell you if they've seen her & help you out - but your asking about our favourite films about prostitution !!
The movie "Discreet" 2008 funnily enough has a plot synopsis that reads :
"Young geek, socially out of depth in the 'man's world' of his job where he is successful, seeks to put his sheltered religious upbringing behind him by belatedly losing his virginity using a 'discreet' prostitute. His sexual naivety, and immature questioning, turn the cynical beautiful prostitute round to breaking her rule (no kissing with mouths)."
Your seriously trying to suggest you might be the character in this film trying to re-enact some sort of delusional fantasy in your own mind ??!! Dear Lord ! Schools out or worse still your institutionally confined with access to the internet - one thing I'm sure of is this : that your just a demented troll
