It depends, do you not like the way he kisses (he is a wet, sloppy kisser), or are you not feeling like any physical turn on? Because sometimes a guy can appear like a perfectly good person as you've described- he is cute, he is nice, you have good conversations, you enjoy his presence- but you're just not attracted, you don't have that "spark". That is totally normal, and in that case, maybe you should just be friends. It's okay to have friends that you love, friends that you admire and think are good looking, but doesn't always mean you have to date. Sometimes it just isn't "right", and you cannot force yourself to make it feel right.
