Presumably I'd flirt, but what the heck is even that? How am I supposed to do that?
Often what I've done in the past when I wanted to come out to someone (my ex-girlfriend waaayyy back in the day), I hinted about that, often in joking ways so I could take it back if a negative response came out. I think that's also the only way I've ever tried to let someone know I like them.
Recently, I think I have realized me being more playful and joking around with people I like. Perhaps that's "flirting". IDK.
...
tl;dr: I don't know how to flirt. I also have a poor detector for realizing someone is attracted to me. They have to do something obvious, like guys using pet names. (which is frustrating, because I don't like that, but what short of that will oblivious me even recognize? Ugh)
Yes, that's flirting.
