Loosing the spark. I am confused

Me and my bf have been together for 5 months (I'm 14 btw, he's 15) and we haven't kissed yet because we r scared (we haven't had our first kisses before so we r newbies). I know 5 months in and not even a peck. It's....different I guess. Anyway I am scared we r getting comfortable and loosing the spark. I don't see much of him but like today it was just off to me. Not him but both of us I guess. I left with so many thoughts in my head. I'm scared we r loosing our spark and I don't want to because I can see him long term (won't say forever cause u never know what the future will change). But yeah. I am scared cause I like him but like idk. We've been through stuff so far in our friendship and relationship and I don't want to loose what we have. I don't want to break up with him but idk. I am really like in the middle of everything.
