I want more sex from my wife of two years
Oh really? Why not ask your partner about having more sex if thats what you want?
She'll just say no to me
Pressuring your partner for sex is not a good idea. You are better off trying to either turn them on, or make them want to have sex with you. Try to be creative and appeal to their love language.
I could use my godly looks to make her horny.
As long as you aren't pressuring her into it I think it's fine. I still think you should just have a chat with her about it.
