Hi. You've been around for awhile, so I hope the bluntness that reigns supreme in this section isn't a surprise. It's almost always kindly meant.
So, to start, one of your chief problems is a 16 year old profile with no certs. You could handle that in multiple ways, depending on the reason for that, but it does have to be addressed in some way. One option is to create a new free profile and contact SLS to move the billing to that one and shut this profile down. Another is to say something about why you don't have certs, if they're something you've chosen not to have. Or you could get certs.
Some folks will debate whether they're useful, but I think they're critical for men playing solo, so you have to do something.
Another tangential issue is that with a 16 year old profile on a site that doesn't automatically adjust your age, you could be 45 or 61. So, if your age is correct and your photos are current, it would be a good plan to briefly note both things down in Additional comments.
As far as your photos, some are good and some just aren't. The naked torso can burn in a fire (sorry), and the car photo with the wrinkled shirt is not attractive, and you could probably prune the rest and come up with another photo or two of your smiling face on top of a full length photo of you fully dressed in unwrinkled clothes that fit, preferably date night attire.
For your profile, it has promise but the way you currently have it structured is kind of a mess. (Side note: If there are a lot of typos here, I'm sorry. I'm tired and can't always catch them when that's the case.)
In Looking For you could expand more on who you're looking for. I'd stick with the positives rather than use negatives as your only modifiers. If that's insufficiently clear, I'd leave off the parts about dishonesty and drama, because that won't keep them away and you've wasted words instead of being more welcoming to the theoretical people you'd like to attract. Talk about them instead. Basically, just lose those bits, move the parts about you to Description, and expand what's left a bit.
Your relationship status does belong in Description, which is a section about you. The part about hosting, instead of sitting up top being defensive, can go down into Additional comments as well, where it's just a thing (and also subtly reassuring that you aren't another cheating husband).
For what's there now, the first paragraph, suitably recast, really belongs in Looking For, because that's what it's about. Start with the bike riding instead, just taking out the weird capitalizations. The last paragraph doesn't belong here, but it's going to need some rewording to fit in Fantasies, which is a better place for it.
In Fantasies and experiences, you have a chance to be relatable and approachable and you...punt. "Ask me" is not an adequate approach. No, you don't have to be graphic - please don't be - but just like with hobbies, this is a chance for you to connect with others. The last sentence is of debatable value. You've said it elsewhere better.
I think you have enough to add to Additional comments to make what you have superfluous, but with just a little rewording it could be the bones of Looking For.
The problem I see with the profile you currently have, over and above the lack of certs and the age of it, is that you aren't shining here. I think that's mostly because what you have often isn't in the right place so it doesn't flow logically. Since it doesn't, it obscures that you're interesting. I'd like to see what happens when you straighten that out, to see if that's enough or something more is required.
I hope that helps. Good luck.
