Catherine didn't really know why she kept going out with all these different men when she had Sara. Well, when she had sex with Sara. Whatever kind of sex she wanted - gentle, rough, slow, quick, whenever she wanted it. And it was always good. So much better than sex with these men. And yet, here she was, again, with some man, letting him undress her, touch her, fuck her. She just couldn't stop doing it. When a handsome man asked her out she couldn't say no. Besides, she told herself, it was not as if what she had with Sara was what you'd call a relationship - of any kind. There had never been any talk of sexual exclusiveness, so really, she reminded herself, she had nothing to feel guilty about. So why was it that when she walked in on Sara and Sofia in Sara's bed she could feel her heart breaking?
