Is it normal that i get so sweaty everytime...

Everytime I meet this boy, I have known for about 2 years now, I get so sweaty I can't control it. Sometimes I even feel a litle light headed. I know the obvious answer would be that I like him I suppose, but I don't even know if I do. I just know everytime I'm about to meet him I start sweating and continues the entire time I'm with him. It has never happened with anyone eles, what are your thoughts?
