Intentionally or unintentionally?
I don't think I've been able to bring myself to intentionally do so. I've considered it.

Unintentionally depending on the subject I might look at him more (by which I mean looking at him at all tbh). That's generally when it feels collaborative, usually conversations in which I'm not feeling super intense shame. That's often accompanied by some light teasing/joking. Generally that kind of lightheartedness is only when I'm feeling that kind of optimistic collaborative closeness.

The closeness like feeling cared about in a less "productive" more "gentle" way (not really sure how to describe it? I really really don't want to use the word "tender," blegh) is something I have a harder time showing and more actively trying to resist in myself. I feel like I shouldn't show it because it feels shameful, or like he'd be disgusted by the idea of that kind of closeness with me.
Clearly I have issues.

I'm interested in how others do that and how they feel about it after. I'm worried I'd be angry at myself for it after.
