I absolutely like the attention she gets, but I'm personally thankful that voyeur picture-taking is discouraged at the beach I go to. My wife, and our friends that sometimes go with us, would be a lot more reluctant if that wasn't the case.
For us, the turn-on is being there and being seen/seeing others. Not so much the less-than-discreet sharing of pictures and possibly faces. Nothing like seeing her talk to different people and seeing her creamy pussy when she lays back down on her towel

I don't think your kink is uncommon at all, though. How does your partner feel about it?
