Am I intimidating to guys?

I never dated before and I’m not sure if guys in the past may have liked me but never told me. And I have a guy friend at my job who makes it kinda obvious that he likes me, but whenever his friends bring it up around me he tries to deny it. But when we’re alone he talks about us being together but we haven’t made plans yet. But he think my brother will get mad at him for talking to me (Which he won’t)

I catch him staring at me a lot and when I ask him about it he’ll just chuckle says “nothing” and walk away.

It happens so often now that I actually feel awkward when he keeps looking at me when I’m trying to work. I don’t wanna report him but I have told him to stop and he haven’t.

In the break room I see him and his friends all huddled up and they would look at me then at him. But like whenever I ask about it he doesn’t wanna tell me and his friends won’t either.

Is it possible he’s shy or afraid I might reject him or scared of my brother? I even told him if he needed to talk to me about something personal he could always come to me but he doesn’t do that either.
