Affection and intimacy

So I’ve been dating someine for quite some time. We used to be much more affextionate and intimate and that has dwindled. I definitely enjoy his company, and holiding hands is great but I miss the connection of more. I am waffling about bringing it up or
Even what i would say if i did. I totally make it all about me – that im not attractive
enough, that im too old. I also get triggered because this happened in my previous marriage as well and that felt like the beginning of the end. Would love some perspective on this and feeling stuck.
