Well when I say cute it could mean the guy is physically cute or acts cute ya know like does something cute. I call guys hot because its too hmm how do I explain this, well you know when you call a girl hot, it makes it seem like you just want to f*** her right? and after her looks but cute is better then that and very wholesome. or something when a guy does that's very sweet I go "awww that's so cute ^_^" I don't look at them as a little brother, I do say adorable too, and if I did then that just means I'm not really into you sort of way, lmao I hope I'm making sense
Can mean two things and I understand how it can be confusing.
Cute can mean attractive if they say it in a short sense (also based on the topic). If they prolong the cute into something that your grandmother would say while pinching your cheeks, then that's the adorable type of cute.
