Adult film title help 2001

I saw a late night cable movie in 2000 or 2001 that had a scene of a woman who is sexually curious and looking for a new experience. She walks into a movie theater and as she is sitting down watching the movie a guy she is attracted to who is sitting behind her or next to her puts his hand up her dress and fingers her. That was the first sex scene. Id love to watch it again but can’t find it based on my searches. Can anyone help? Thanks!
