My boyfriend is very vanilla

So I’ve been dating this guy almost 2 yrs and I’m absolutely in love with him, but he’s very vanilla. Obviously, I’m not going to leave him because of that but I want him to be a little more kinky. Last night was my 21st birthday and I was drunk (lol) and started telling him all kinds of things like I want to be his bitch and I want him to tie me up. We fucked and he went down on me for a little bit which was really nice, but that’s the first time I’ve really ever actually told him what I want. Does anyone have any advice on how to start bringing some kink to the bedroom?
