She says she wants me to be her daddy

But I think she just wants someone to be her daddy. I’m insecure and can be a bit self destructive at times. She knows this.. why would she ask me to be dominant? Why would she trust me with that? I dont deserve it. I might be a control freak on some topics but I’m definitely not good enough to be someone’s dominant. I don’t even see why she’s with me. Me as a dominant would pretty much just need up with her fucking other well endowed men. Real men! If your phallic is the representation of your manhood. Then I’m just a few inches from being a woman. Just wish I would’ve learned all of this sooner.
