Movie shown on channel 5 in UK in 2003-2005

[Voctor]

Hello,

I am trying to find out the name of a movie which was shown on channel 5 in UK in period 2003-2004 on Friday night (soft porn).  The movie is about a guy who has sex with a woman on the day of his batchlors party.  Later after many years, he goes with his wife to spend holiday with his friend & it turns out that his friend's girlfriend is the girl whom he had met on the night before his marriage. Finally he comes to know that this girl is actually a prostitute & the entire setup on his batchlor's party was done by his friend. Anybody remembers name of this movie?

I don't remember the name or any of the actors in the film since I had seen it many years back.

Please help.
