Hi. I don't actually agree with Velma. It definitely is easier if you fill some fantasy niche, because there are way more guys than couples and women looking for them, but if you can build a friend group the lifestyle is ideal for anyone who is looking for non-traditional sex. It is just that the odds are worse here than they are on Tinder, etc. In person is easier than online, which is why the standard advice is to find clubs and parties that allow single men. But, you know, pandemic.
So, as far as your photos go, you have the right idea with the non-selfies (those can just go) and the great smile, but your clothes don't exactly fit well. Not your fault that it's a pet peeve, but, really, there is no reason to wear shirts that you could easily hide half a kindergarten class under.
Taglines are meant to generate sufficient interest that people want to open your profile. Yours gives too much information and eliminates the need to do that. So, change it to something short and, if possible, clever. Steal if you can't think of anything. Hell, if you're even a tiny bit nerdy, steal mine.
Okay, here's what you have in Looking For: "Looking for couples and females. I like to ensure the woman is satisfied. Interested in an ongoing situation or NSA. I am open to new experiences and fulfilling couples, or a single woman's fantasies. Enjoy many types of play situations in the lifestyle."
Okay, most of this doesn't belong here, because it's about you instead of who and what you're looking for. That difference is not subtle. It's also too...not passive, but maybe insufficiently assertive. It's a good thing to be a nice guy who wants to please, but if you aren't careful it slides over into too much eagerness to please and that's just exhausting.
What about "I'm looking for couples and women with fantasies I can fulfill?" You'll need more, but it doesn't have to be more than one or two more sentences. Just a little bit about the kind of people you're looking for and what you're looking for (NSA, on going, whatever).
In Description, concentrate on the kind of person you are and your vanilla interests. Definitely mention your six years in the lifestyle - bonus points if any of that was as a couple - but not your sexual predilections. You can leave out the exhortations to have fun! too. What makes you unique and valuable is not that you like oral or love to please, but the concoction that makes up who you are. That's what goes here. Don't waste words talking about your height (it's in your toggles), your shoulders (in photos) or hair color (ditto). Don't use tired tropes like SWM either. Being able to enjoy good music and engaging conversations though? Yeah, that's gold.
In Fantasies, cut some of that down. I like the way it cuts across how wholesome you appear to be, but there's too much of it. Also fix whatever it is that is causing weird gaps in the text and add an extra line in between paragraphs. Oh, and being "open minded" when your cert talks about MMF is generally going to be taken as a signal that you're heteroflexible, at the very least. If you aren't, I'd just leave that phrase out.
Additional comments is fine, but if you want to say something about liking to please, this might be a good place for it.
Basically, if I had to guess, you're just a little too passive in the way you've worded your profile and your photos could use an upgrade, but if you tune things up a little and carefully pick the people you contact, you might do pretty well even now.
Good luck.
