How do I tell him?

So I’ve been talking to/hooking up with this guy since the summer and the sex is amazing but there are things that I don’t really know how to address. Like he has never given me head, which is okay, because I’m bi and tend to compare head from a guy with head from a girl and I really don’t want to end up comparing him to anyone else, but he’s never even attempted it or talked about. But he asks me for head and I really hate doing it, and since he’s the first person I’ve given a bj to, i still feel like i don’t know what I’m doing. He’s also the first person I’ve ever done anal with and I feel like I may like it more than I should. I don’t know how to tell him that I want to do anal more without fearing what he may think. What are the best ways to bring up conversations like this ?
