First kiss

I’ve been dating my boyfriend for 2 months and we still haven’t kissed. He tried twice to kiss me on New Years and I turned my head the first time and the second time I kept my mouth shut. I want to kiss him and he wants to kiss me but I’m scared to. I’ve never kissed someone and don’t want to mess it up or something. Is it okay to keep waiting? Or am I making it too big of a deal?
