AITA for feeling uncomfortable with my pansexual friend’s repeated flirtations and comments, even though I know he’s just joking?

I (21M) have been living with my friend (21M) and a couple of other roommates for the past four years while we study at the same university. We’ve always gotten along really well, and we’ve been through a lot together. He’s pansexual and I’m straight—there’s never been any issues about that, and I’ve always supported him.

But here’s where it gets complicated. Over the last couple of years, he’s started making comments and jokes toward me that feel like flirting. At first, I brushed them off as harmless fun because we’re close, and I know he doesn’t mean any harm by it. But lately, the comments have gotten a bit more frequent, and they’re starting to make me uncomfortable. Some of them are sexual or just kind of inappropriate, and while he laughs them off, I don’t always find them funny.

To be clear, I don’t think he’s doing this to make me uncomfortable on purpose, and I don’t think he’s trying to push boundaries in a serious way. But at the same time, I’ve hinted that it’s starting to bother me, and he hasn’t really stopped. I don’t want to make things awkward between us or ruin our friendship, especially since we still live together. But I’m also not sure if I’m overreacting or being too sensitive about it.

So, AITA for feeling uncomfortable and wanting to say something to him about it, even though I know he’s just messing around?
