Michelle Rodriguez says it is her "business" if she wants to have sex with a girl, a boy or a dog.The former 'Lost' star - who is rumoured to be bisexual - hates the attention surrounding her personal life, and wants to keep her relationships private.She said: "I don't answer those questions. I just keep it to myself and it's nobody's business. If I want to f**k a girl, a boy, a dog - that's my business. That's why there are bathroom doors."What the majority of people want to know is what I'm doing with my vagina, and I think that's sick. What do you care who I'm dating? I can tell when somebody just wants to know about sex. And it makes me sick."I picture those people turning into pigs, slime coming out the side of their mouth, and I picture them jerking off."Michelle also said her tomboy attitude may be responsible for rumours surrounding her sexual orientation.She added to Latina.com: "I think that they wonder because I'm such a tomboy. And I don't care about what I look like most of the time. You'll see me walking around in my jeans for the most part. I'm pretty much a tough a**. You don't see that type of s**t in a lot of women."
