I get you. We had a lovely wedding but I photograph terribly, I always have, even before I utterly despised my appearance and was merely self conscious. If I'd had my way I'd not even have had a photographer! I'm glad I now have them for the memories even if I do heavily control which ones people see of me. I'm glad we have the photos of everyone else, of the details etc as well. There are so many parts of the day that are worth capturing and you will look better than you think, I promise.
Things that helped: I declined getting ready photos and arranged for the photographer to arrive not too long before the wedding started. DH declined them as well. There are a few taken of everyone ready and smiling, my dad seeing me etc but that's it. That time felt vulnerable. Similarly there are a few of DH waiting for me and greeting people but nothing earlier.
We asked for no photos of the ceremony except for those taken by the photographer. I didn't mind afterwards as most people who wanted pics of/ with us posed the shots and people sent some lovely ones of our cake, decor etc.
I told my photographer that I expected to drink, snack and socialise during the reception and I wanted photos of everyone else having a nice time as well. Not to spend hours freezing on a lawn squinting at DH in low sun. We did posed pics and she did borrow us for a bit but she definitely took as-it-happened guest pics / us with guests as well and gave us a break!
We also picked a photographer that had a vibe we liked. We went for someone we knew took lots of photos of everyone and focused on fun, naturalistic pictures of the whole day as well as taking some posed ones.
