Hi. Constructive criticism is in the eye of the beholder, but my comments are kindly meant.
Your tagline is fine, but if you change it, clever/funny is more eye catching than sincere. You might want to change your age range to put yourself closer to the middle of it instead of young enough to have provided you with multiple grandchildren to within a few years of your own ages. Your photos are actually appealing in the way they're structured, but I think you'll have better luck if his hair looks combed and his beard is trimmed. If you'd rather not, it's fine, but the general impression to make that is most likely to be successful is that you're ready to go on a date.
In Looking For, you need more text. The section is pretty much about the people you're looking for, centered on them. Saying that you're looking to have fun and meet the like minded (nobody really knows what that means, btw) doesn't do that. At the very least, say that you're looking for couples and solo women that could also potentially become friends. And then two more sentences about those couples and women.
In Description, instead of too little info, you've provided too much. Not too much info, but too much text (it's best if the sections closer to equal in size), and some of it belongs elsewhere (the information that you, Jen, are the one managing the communication on SLS). Also, some of it belongs nowhere. There is no point at all in telling people to respond. They won't and the scolding implicit in the request will turn people off that would otherwise be more positive about you.
That whole last section, beginning with not being models (your photos do a better job than words) is just filler and can be cut, although you can probably make a decent tagline from life not waiting.
For the rest, tighten it up so there's more about we and less about the two of you as individuals. Like, yes, it's good to know you have individual hobbies, but the rest should give the impression of a unit. And maybe do paragraphs instead of sentences grouped two by two.
In Fantasies, the acronyms for threesomes might need some work, since the center place is meant to indicate who the focus is on. So, ffm is different than fmf, etc. Otherwise, same thing about the paragraph being a better approach, and the commentary on how events seem fun can go, since fantasies don't really need an explanation and giving one makes your interest sound pretty tepid.
In Additional comments, that's where you put that Jen is the communicator. I'd also leave out this: "Would like to hear and possibly meet with those close to us." Are you indicating you're not really serious about meeting people? Or is this a way of saying that you're looking for couples and women in your area? Because if it's the former, you might want to pause your online presence until you've been to a few events and decided it's for you. If it's the latter, that belongs in Looking For.
Best of luck. I hope this was relatively painless. I'm happy to explain anything that doesn't make sense or needs more background.
