Was he flirting?

Silly question but I was talking on voice chat with this guy that I’ve been seeing (from what I understand he either never had a girlfriend or just had one in high school so I have to give the first steps but he’s been staying at my house almost once a week where we cuddle all night; last time I kissed him, but just a peck before sleeping). And he dresses really nice so I asked him if he knew any shops that sold cool hoodies so he laughed and told me “I’m not giving you mine” (in a tone as saying “I know what you are trying to do) and I got so flustered because i was genuinely asking where to get one, I didn’t even noticed he had one. Was it an indirect way of saying he wants me to steel/wear his hoodie?
Last time he stayed at my house he stole some cosplay kitty ears I had, he was wearing them and when he was leaving to return home I reminded him that he was still wearing them and he told me: “I know, I’m stealing them” and he literally wore them on public transport till he got home.
