This was on HBO, Showtime or Cinemax in the late 90s ('96-'00). It was a sci-fi or some kind of thriller, I believe. The first scene that I recall is of a young man walking into this bright light, then appearing somewhere else. The next scene that I remember is a sex scene with a young brunette woman and a man. During this scene, their activities are interrupted by a television monitor coming on, and an older man giving the woman information, instructions, etc. She was an assassin or a secret agent or something. After the tv went off, the guy she was with attempted to start things up again, and she hit him across the face and told him that if he touched her again, she'd kill him.
Any help that can be provided, I'd appreciate. I'v been looking for this movie forever; I was, in the interests of full disclosure, quite intoxicated when I saw it...
