Valentine's Day

I'm 16, I'm not ready for sex I know that but for Valentine's Day should I do something with him that isn't all about sex or would that be a bad idea since I'm 16 and he is 17. We have been together for 4 years now. We have kissed, made out, but never anything down there if you know what I mean. I am just asking because I'm not sure and I want some opinions. Thanks x
