now i don't hand out sexy "hey's" and what not very often, usually only for guys that i'm really liking, and one time i passed this guy i thought was super hot and said hey in a sexy voice, and it seemed like he was responsive and liked it, as he smiled back and was like 'sssup.' just wondering, do guys actually notice when it's sexy and not just a normal hello, and is it helpful/useful in letting them know you're interested?! some feedback on this would be cool.
