Help ID hooker monster sex on a bench
 

Hi. I'm new to this forum, so hi to ya all.
The reason I registered is the burning desire to ID some of the movies. This is complicated by the fact I didn't see those movies, just stumbled upon unanswered questions on other movie sites.

One of the most interesting question is.
It's a movie from no later then end of the 90-s. There is a guy who gets into a bar. Talks to the bartender, looks around and notices a girl who is probably a hooker. He picks her up, they cross a dance floor which is open-air, find some bench on a street, and this girl starts jumping on the poor fellow. First he is pleased, but then she moves faster and faster, eventually turning into some kind of an animal or a vampire. She kills the guy in the process.

This is not Species, not Decoys, not "Don't be a menance..."
Please help.
