To give you another perspective and experience .
I moved in with my now dh 6 months after dating. It was his flat owned by him. As I was already living in my own rented place I moved in the furniture that was important to me and useful (wardrobe, chest of drawers, desk) because he now had a spare room we had a bit of space for it all.
However as it was his place I knew I couldn't change the decor or make any demands on him.
The furnishings in the bedroom were... lacking .. bed was old and slatted, curtains threadbare. So I encouraged him to go to the shop and buy new curtains etc and went with him to advise, but the colour choices and style was all him. Re the bed, after conversation he realised my bed was much better than his so agreed to switch.
After a few months I casually pointed out things he no longer used and how it would be better if we changed it. But we only did things he wanted to.
All this time I was paying my contribution of rent and towards household Bill's (think I paid for food) do proportionate to my earnings.
We had these discussions before I moved in, I was clear about my financial position and how much I could afford.
I also saved him money by looking at his providers and getting cheaper deals.
After a few more months we got engaged, and then decided to get a place together.
Guess what I am saying is that it is his place, and yes he should allow you to move in your things and have those out within reason but ultimately it is his property in his name and so he does get the final say. It doesn't mean you cant sway what he chooses and he should still be letting you be comfortable (I demand 300+ thread count bedding and have never relented on that even when I moved in.... dh realised what he had been missing out on)
I would be concerned if he doesn't let you display any of your possessions or furniture you want to keep.
