I'm stuck in a reverse beast world

I was just an ordinary teenager until I decided to act on a dare and here I an, all stuck in a new world. To make matters worse, the world is filled with beautiful women wearing skimpy shirts and skirts and I'm GAY!!!
They can transform into animals and want me to be their mate. How can I be their mate when I am G-A-Y, GAY!!!.
They might try to turn me to the other side, I can't stay longer I have to leave this place!!!

"I thought you said you swang the other way" She says.
"Pfft me, I was lying. I was trying to save myself for you" I say.
"Hmm, maybe you are bisexual" She says.
"No! I am straight. As straight as can be, like a ruler" I say.
"Hmmm" She says sounding totally unconvinced.
Why did I say I was gay. I am clearly not gay. Can someone please explain to her that I am straight and not gay.
