How to understand men?

I've talking with a guy and he's always complimenting me. We talk almost all day and he compliments my looks, my stories, my body and sometimes he's acting a bit too 'sweet' like he often says how much he'd like to see my body more, how much he loves my lips, my chest and he sends messages like "Holy shit. You're so fucking hot.", "Fuck.". Stuff like that and when I thank him, compliment him back or I tell he's too sweet he says he's just like that, friendly and that he doesn't like to put people down and he's just genuinely. I'm getting mixed signals, I don't know what to think.
