My man is really mild mannered, and doesn't exactly take control in the bedroom. That's fine sometimes, but I mentioned to him that it would be really hot if he took control and was more dominant sometimes during sex. He is when we're texting about what we want to do to each other, but not when we actually have sex. I don't know how to encourage it/make him feel more comfortable with the idea?

Edit: I have told him what I'm into
