S.O. Childishly poking other people of the opposite sex

Spouse of a year, in his 30’s and has a 12 week old on the way sees no problem poking at other women and thinks it’s funny.

I’ve brought it up that this hurts my feelings yet he “forgets” after a long period of time. So to me how do I not feel a bit betrayed I truly want to understand how it’s ok?

I’m self aware of possible attachment trauma I know it’s not black and white I don’t freak out when he’d shake hands, fist bump, or hug hello and good bye but that’s my line and obviously not his. His excuse; it’s just who he is which I can’t just bring myself to accept when he knows it hurts me.

He knows my traumas and that I “practice what I preach” because I have no hesitation confronting other married people who use the excuse “is it wrong? it’s not like we f@*ked” like why is that even an option as a line crossed as a married person it should be several steps before that. I have guy friends too and my husband knows every one of them and I keep my hands to myself. If I do it’s a last resort never to be confused as a kind touch.
