We haven't formally discussed this as being a master/slave type relationship, but I'm just so into him telling me what to do and controlling me. He has such power over me, yet he's never once abused it. All the things I craved for years, I'm finally getting.
May I ask how you got to the point where you are now? Didn't you talk about this?
(Btw, what does FWB mean, exactly?)

I want this to go further, but I'm not sure it's my place as sub to initiate the conversation.
If a sub cannot initiate important conversations, then communication cannot flow, and as both denuseri and Leo9 (and many others during other threads) have pointed out, it is a MUST for every relationship, no matter what kind.

Furthermore, a sub or slave has a duty to share things with their Master, not holding things back! How can you expect anyone to be a good Master, if they do not know everything about their slave?

As den says there might be a risk, but maybe not a big one, seeing how you are already half way there.

I'm not sure if he'd even want to take it further--he's a very nice guy, and sometimes, it seems like he feels like he's an asshole or something for wanting to dominate me, even though I enjoy it.
Then at the very least it should be a relief to him that you really really enjoy it :-)
But if it so happens that he doesn not want to take it further, well, that must be respected as well, right?
And if he does, can you give him some time to get there? Even if you are very hungry? (A well known situation indeed.)

I'm also concerned about how the FWB situation fits into this; it's been going on for quite some time now, and we are both content to keep things commitment-free. I may want a master, but I have no desire for a "boyfriend" right now

Any advice?
There I have no opinion or advice, except never mind what others do, create your own style.
