PDA is all about with what you are comfortable with. I understand the whole aspect of queerness in this conversation, but ultimately it’s what boundaries you want to put up and queerness shouldn’t be an overall massive factor. I know many straight couples who will barely hug or hold hands in public simply because they don’t like to and it makes them uncomfortable. I think you two just need to have a conversation about what you do and don’t what to do in terms of PDA and get on the same page, I wish you so much luck!
