Selma Blair practiced lesbian sex scenes in private with 'Heroes' star Stana Katic.The 'Cruel Intentions' star - who shared a lingering same-sex kiss with Sarah Michelle Geller in the teen movie - plays a lesbian again in her new movie 'Feast of Love'. Stana revealed: "We rehearsed our love scene quite a bit in a private room together. We both looked at the bed, looked at each other and walked into the room and went at it."The 29-year-old Canadian actress - who plays sexy bad girl Hana in the hit US TV drama - enjoyed kissing and fondling Selma, 35, but still prefers kissing men. She told Steppin' Out magazine: "As a kisser, I would say Selma was very titillating. It was my first time kissing a woman and I had a great time with her. But I reconfirmed to myself that I'm 100 per cent heterosexual."
