Is it normal to have a crush on my friend of the same gender?

One feminist publication stated that there is no such thing as a "straight" woman, that all women are lesbian or bisexual. I actually believe it because I've seen women turn lesbian, at least temporarily, on whim. And one lesbian who disguised herself as a man had women still wanting to be with her even after she told them she was a woman. I think women will spread their legs for anyone who knows how to manipulate them psychologically. And I'm revolted by it. I'm a firm believer in gay rights but I think the ability of women to change their sexual preference only proves the stereotype of women being capricious.

Sit on each other's face and eat each other's bald cunts until you both cum and pee in each other's mouths and deep rim each other's brown eye puckered poop chutes until you both fart and shit on each other's face and top it off by sucking each other's tits covered with whipped cream.
Then wear strap - on's and fuck each other's twats and shit pipes and then suck the dirty strap - on's until they are squeaky clean.
