Is it normal that cheese is like an aphrodisiac to me?

Ever since I was a kid, I have always LOVED the taste of cheese. My love for it grew as I got older, and now it has a strange effect on me. When I eat it, I feel like I'm having an orgasm or something. Literally. I get all tingly down there. (TMI lol)I have even received oral while eating cheese. It was amazing!!! This is weird, isn't it? I am addicted to cheese and don't know why. Is it normal?
