I've been with my girlfriend for over 2 years now, and I love her but theres a couple things she doesn't know about me that I wish I could tell her, but I know for sure she would leave me.  Basically she doesn't know that I'm bi.

 She doesn't know that I love to suck cock, I love the taste of cum and the feeling of cum on my face.

 She doesn't know that I love to be pissed on, and would love her to piss on me as well.

 She doesn't know that although I've never been fucked in the ass, I would like to be.

 She doesn't know that after we have sex and I cum inside of her, that I would love to eat the cum out of her pussy.

 She doesn't know that I would like to be dressed up like a female while all of the above is happening to me.

 I wish I could tell her, I wish if I told her she would like it and want to participate and experiment with some of this.  Alas, I know she wouldn't approve and that she would leave me if I did.  So here I am, telling people I'll never meet some of my biggest secrets that have been trapped in my head for years.
