I have to revise part of what I said earlier about Nina Hartley's Making Love to Women. I remembered part of it incorrectly. It actually starts out with Nina and a woman friend. The first segment is mostly lots and lots of dialog (
very good stuff for both men and women to hear). The second segment is a very seductive, gradual, sensual scene between Nina and the woman. It's playful, sexy, and real. The third segment is another very erotic, gradual, very sexy scene with Nina and a man on a date. Each of the sex segments are longtime scenes, lasting just as long as really good sex does.
