How to be more affectionate?

My husband grew up in a loud and affectionate family. I grew up in a quiet and not so affectionate ( we love each other but we just weren't huggers, kissers, etc). While I thought I was doing good to my husband, I guess I am not.

I can not handle the loud. I try very hard but it honestly just hurts my ears so much and then makes me not want to be in that area.

I try to be physical enough for him but how it seems is he wants me to touch him 24/7 and vice versa. Sometimes I just need my personal space. I'll of course hold his hand at times, hug him at times, and we do have our alone time at least 3-4 times a week.

How can I do more for him and grow to feel comfortable and normal with it?
