Most Helpful Girl
About the labels... don't judge him by what others say, find out for yourself and if he does turn out to be a player, don't kid yourself in to thinking you're the one that can change him. For now, you like him, he likes you so just see where it goes, no one is doing anything wrong.
As for the shyness, sure you are shy but from the sounds of it, he is not. So yeah it might be a bit awkward the first few conversations but once you get past that and feel more comfortable you'll start to relax more, trust me.
Just enjoy it and if something blossomed out of you and him, great but try not to fall head over heels for him JUST IN CASE the rumours are true, you don't wanna hand yourself out to him, get to know him and in turn let him get to know you. Good luck!
