First boyfriend (Advice welcome)

I am turning 15 in 5 days and I got my first boyfriend 24 days ago. He went to my school and we were just friends but over the summer his ex-girlfriend and him broke up. So we were talking and he admitted he had feelings for me. He is being the absolute sweetest to me and we sleep on the phone every night, but now he lives an hour away and is going to a different school next year. We went on one date, it was to the movies and we held hands and hugged and he kissed my cheek. (I'm not his first girlfriend but he's my first boyfriend ). I'm absolutely terrified of doing even the simplest things like kissing him. I have not even had my first kiss yet. I trust him, and he is shamelessly honest with me, and I guess it's a bit unusual that I'm almost 15 and never even had my first kiss.(no judgement). He isn't pressuring me into anything (we barely even see eachother anyway) but I am just really anxious because I'm going to see him possibly in a few days and definitely in 5 days, but I'm just in need of like reassurance and talking down basically.
