Is Hillary Clinton a Lesbian?

It could be that she is a Lesbian, or at least bisexually if one believes the statements of some lovers of her husband, Bill Clinton. According to the statement of one of his lovers, Bill Clinton shall have said the following about his wife: "She has licked more twats as me in my whole life ". (original quote)
Since Hillary often was with her husband in Europe and she has studied at a woman college, I regard it as possible if not even probable that she is bisexual or lesbian. Your comments on it?
