Healthy relationship advice

I (22 F) travel for work. I met my bf traveling (22 M) we’ve been long distance for almost 4 months and things are absolutely amazing. I’d call it a healthy relationship, but it’s VERY hard for me considering this is my first healthy relationship and I have no role models in my life to see an actual healthy relationship.

Problem is I’m his first real relationship, he’s shy we’re kind of on different levels and time. As in I want fast and hard and quick meaning I want kids , move in together , preferably in the next 5 years Max. He’s very slow moving says it’ll happen when it happens type deal.

My issue is this week I’m off I drove 20 hours to see him essentially. From south Texas to Nebraska and I’m disappointed to say the least. Nothing is wrong with what he’s doing per say but I was wanting all the attention to make up for those weeks I was gone. IE sex lots of sex and cuddles and kisses and him spending the night. It’s Thursday and we had sex once that I started.

Idk if he’s shy but I’ve been gone 4 months he knew what I wanted and we had talked about it and I’m just disappointed I’m not getting the attention I wanted and I don’t know how to bring this up in a healthy way I just keep getting mad at him and he’s asked what’s wrong I just don’t know how to tell him without sounding stupid..

edit:

Also wanted to address pictures. We had no pictures together so I brought up taking more together and I’ve been taking photos of him and posting them but he hasn’t posted me or isn’t taking photos of me/ us.

I’ve brought up the social media and he keeps saying he will , etc ..

I don’t think he’s cheating on me at all I see no red flags but I just can’t help but feel disappointed and a lot of rejection even tho everything else is okay.
