name='dozo']I saw this film about 10 years ago on UK terrestrial tv (Channel 4 i think).
The plot ran as follows: A guy was about to get married and his friends made him a stag-night party (like all good mates do). Then 1 friend introduces him to a call-girl (prostitute) as a "pre-wedding" present. They obviously go off and have fun, but he falls for her. Even after he gets married there are various scenes of them together (sex scenes - but this was NOT a porno), including one i recall by a swimming pool. Then his wife spies them, and goes off to his best friend as a sort of revenge.
Any ideas i'd be greatful.
