Is it normal that i get turned on by taboos

I'm around 2-3 on the Kinsey scale, and I get turned on by weird things.
I get turned on by incest even though the thought of doing that with my own family is my #1 turnoff. I get turned on by gay porn or males masturbating even though I wouldn't personally think of doing it in real life. I get turned on by transexual porn even though I'd run from one in the alleyway. I get turned on by bestiality (only when the human is female) even though I wouldn't think of doing that in real life.

It seems like I search all this weird porn when I'm in the heat of the moment. I never go onto the computer with a clear mind and go 'Hey, let's look up some bestiality!'. It's always a guilty desire of the dangerous and the forbidden.

So... Am I normal?
