I'm scared to make a move incase I make a fool of my self?

Ok so I'm seventeen and have never had a boyfriend before. I'm not ugly or anything, loads of guys had fancied me but all theu wanted was sex and i wasnt ready seeing i had difficulties dealing with my mums death for the past couple years so I've just not been into relationships. But this made me feel self conscious. Now there is this guy who likes me he is uber cute and I like him too but I'm worried because I've never kissed a guy before and I don't want to make a fool of myself but if I don't plug up my courage now I doubt I ever will.
