What am I feeling? long distance boyfriend or new coworker?

I am getting right on it: I am in a long distance relationship for over 2 years (online, have yet to meet up) I am happy with him, we trust each other. Can tell each other everything and he makes/made me feel some type of way (as much as you can do it online/ text, facetime etc.) I've met a guy at work who is very outgoing and friendly to me. I haven't had that much attention like that in forever. It's weird cause this is in person. It's not that I am feeling in love with that guy but I am really looking forward to talking to him. He makes me laugh. (we just met, worked together for a week) This (long-distance) relationship is my first ever. We both invested hella lot into this. I suspect I just feel that way with my coworker cause that guy is in front of me and my boyfriend is so far away and it tricks my mind that one is better or more exciting than the other relationship. I am rarely hanging out in public places where I interact with both sexes and that in my age, so that's why this is also new to me. Is it something I should mention to my boyfriend. How am I supposed to deal with it? I already asked myself what if that coworker is interested in me, how would I react? I sometimes miss this physical face to face with my boyfriend. Especially since we never met. We never experienced certain things yet like just being in front of each other and talk and stare at each other... I don't know. I'm in my 20s by the way.
