What does he mean when he says this? short!!!?

so ive been loosely talking to this one guy, we haven't done anything yet except a lot of flirting and hanging out. he's EXTREMELY flirty, so we were texting and he asked what I did this past weekend, and being truthful I said I played strip poker with some friends (not in a sl*tty way, with friends since I was little, i'm 19). he was like "Yeah but what did you have to show their eyes is what I'm worried about." is that him being protective of me? I know he's super flirty and outgoing, but could he possibly like me for more than just a hookup?
