FUCKBOY OR NAH??

So I have been talking to a guy for around a week and he is incredibly attractive. He doesn't go to my school but he hangs around with some of the very popular people, so he may be a fuckboy. He is pretty nice but sending off wierd vibes? He asked me if I had ever sent nudes and I said yes once and then I asked him and he said yes. I sent him a photo on snapchat in my bra, but that isn't really that bad, since I wear bikinis all the time, but then he sent me a photo where he was completely naked with the drawing scribble over his penis. I talk to him all the time and I am starting to get feelings for him, but when I say he's hot he says thanks but he never says it back? And also sometimes he snobs my snapchat that I send him, so I always have to start the conversation.
I just want to have your opinions to see if you think he is actually a fuckboy or if I should keep talking to him? I have nothing to lose?
