unfortunately, no :(
i remember one of the main characters was a photographer and wore a headband, his hair was long-ish, i think he was openly gay. the other was supposedly straight. both had light hair. and the straight guy met two of the gay guy's friends at one point and they got him into a menage-a-trois type situation, making the gay guy jealous. i think one of those friends had long dark hair and a goatee. pls help me find it!
