Hi. I'm just going to be blunt. It's well meant and about your profile, not about you, but stuff like that can still sting, so I apologize in advance.
Your tagline is out of date and it's too long. When you use time sensitive wording anywhere in your profile, you need to remember to update it. Also, please go for short and snappy instead of so informative that no one needs to open your profile, something your tagline is meant to encourage.
I do not love public nudes or lack of variety. Any chance you could take some smiling photos of you in unwrinkled date type clothes that fit? Also, since your age and your photos don't seem to relate well to one another, if the pics are current as of this year, put that in your profile. If they aren't current, please replace them with those that are.
You are dealing with preconceived notions about your age, so you need to be clear about who you are now, including what you look like. And certs would help with the notion that older men invariably have ED.
The text of your profile could do with being read out loud to catch and correct the less than flowing prose.
To get to specifics, there's no reason to have that last sentence in Looking For, because it has nothing to do with who and what you're looking for. Put it in Description instead. And there you can lose discussion of hobbies you don't have. I mean, I've looked into needlepoint, but my chances of ever doing it are zero, so talking about it would be, at best, a yellow flag.
I don't love most of what you have in Fantasies, but I can't tell if it's because it's too flowery or because I don't like the writing style.
Additional comments, which would be a good place to put that your photos are current (if they are), instead mostly just has stuff that goes in other sections or is ridiculous like that black ring chain letter nonsense. You find other swingers by going where swingers go rather than by trying to start a movement via a cut and paste in what is supposed to be your polished, interesting advertisement to potential partners.
Anyway, good luck. I hope you make some changes in your profile, but your best bet is to meet people at parties, meet and greets, and clubs.
