I'm curious how you're reacting when you think he's dropping hints? Are you just ignoring it? Or are you playfully flirting back? How open (or chill, or relaxed, or playful, or all of the above) you come across is likely going to impact his comfort level if he is curious, and if he's not curious, well then you're at least both enjoying being flirty and relaxed with each other.
Everything everybody's said above re emotional aspects, potential friendship impact (good or bad), etc is still sound advice, but a bridge to cross (or not) once you're both on the same page.
I've had numerous roommate/friend situations where playful flirting is part of our bond and just fun. I've also had them where they escalated (pretty much the entire first couple years of sexual experience were defined by me presenting myself as open to it/down for it to curious guys). I think I was probably in a different headspace from you; I've always been very relaxed and chill about sex and letting it just be fun without turning into a relationship or needing to impact friendship. In blunter terms (lol) I tend to hint/imply that I'd be down to suck a bud off or get fucked even if it's just playful flirting etc, and I don't require reciprocation so that's usually implied or said outright too. So for guys that have been curious it's planted the seed of thought; not all acted on it obviously, but the ones that did or pushed the envelope with me have ended up getting every drop of cum drained out of them lol.
Point being, my receptiveness and playfulness and relaxed state of mind is what moved the needle with curious guys, and also didn't move the needle with the ones who were just messing around.
