Wtf???

Recently I was talking to a guy friend and he sent me a picture saying "Nudes ;)?" And I was like ok... cause I thought he was kidding around and I sent one back saying "Isn't it past your bedtime?" And then we just started textin and he just kept bringing up nudes and stuff but like he's really just my friend! Like I've talked to him about guys that I liked and he told me about girls he liked and I don't see him in that way at all. He said he was just "joking" And that he was high but I don't really know what to think of it. Do people joke about stuff like that?
