PDA?

For a good portion of my life, PDA has always been kind of meh for me. Either participating in it or watching it in front of my eyes.

I've asked friends to cool it when they're basically finger fucking their girlfriend at dinner and been told that I'm in the wrong and I should just deal.

I've grown a lot over the years and it doesn't bother me quite as much, but I still struggle with it sometimes, both being a participant and watching a partner display that with a meta. Perhaps I need to do more growing. I have been to kink events where you can watch people doing various "activities" and it didn't bother me too much, although I would remove myself if I got uncomfortable and go to other areas of the party, like where food was. I never asked someone to stop at a particular party like that.

What understandings do you have around PDA with partners? In private or shared spaces? At places like the dinner table?

I've been considering if something closer to parallel poly would help me more, but I do have times where I do enjoy being around metas and the community.

I grew up in a home where there wasn't a ton of physical affection shown. My dad made efforts to try and not end up like my grandpa, never showing any affection. But it wasn't often I would see my parents do more than a quick peck, or hold hands. So that was my "normal" for a long time.

What are your experiences? Should I make more of an effort to try and be comfortable with PDA? Do you draw a line anywhere?
