Relationship Problems

I have a problem, my boyfriend is always horny but I dont want to have sex already. He's always talking about us moving forward in the relationship but I dont want to have sex until I get married. I get upset because he's so nice to me and I dont know how to make him happy without having sex. Any ideas?

I tried to give him a handjob but he gets so horny and wants more and I dont know what to do.

Heeelp :c
