Is it normal for me and my turtle?

I have developed a strong attraction to my lifelong pet turtle. I was 18 when I started to take it with me to nice reasturants alone and go for midnight drives down hollywood avenue.. And I was 19 when I started to get physical with my turtle (I.e kissing hugging) but now, I want to go the extra step with it. Is it normal to develope sexual relationships with turtles? I've asked my teachers but all they do is kick me out of their class.. So much for being able to talk to them for advice :(. please help
