Boy names

We recently found out we are having a boy. My husband has the name Steven Douglas Gott the 2nd, and he insists that I have no say in our sons name. My son has to be the 3rd. I don't think this is right. We should make the desicion of naming him together. And the more I push his name away the more he is pissed. He likes the name Sawyer which I do like but when it comes to settling on that name he changes his mind back to the original name. He keeps trying to make me feel bad but he is pretty much telling me I have no say about something I do find a big deal. The other name I really love is Sebastian. Well am I wrong for wanting a cute original name for our first born son? Or do I give him what he wants an be annoyed?
