How to?

How do I boost my guys confidence in the bedroom and get him to try new things? He was a virgin before me and I have had a few partners. He is much younger then me (he is 21 and I'm 28) and just lacking in confidence in the bedroom. He is a gracious lover (always wants to make sure I came) but he never wants to try anything new. I tell him harder he barely does it. While.i love him making love to me I just want him to fuck me. Hard and fast and just....I don't think he has much confidence in himself? How do I help him?

I flirt with him and he blushed alot..I suggest things and same reaction...
