What does this opening line mean???

It's "It's good to know who you are" Again.

I don't live in the moment to say I was Spontaneous but for the simple reason It's who I am. Not what I want to be.

I chew on my Fingernails and spit them on the floor, hoping they'd grow into Money Trees.

I don't like people knowing I have a big dick for the simple fact they always want to see it and I'm scared it's magically disappeared.

I fingerbang myself in the bathroom.

People say I have tourrets cause I twitch a lot. I'm scared to say I do and that it's minor cause I dated a guy with tourrets once. I made fun of him cause he's a horrible lover and called me fat for no reason.
