Hi. My condolences on the loss of your wife. That must be hard. I'm glad you are willing to put yourself out there as a single.
But if you've been a swinger previously, you know it's not easy for a single guy. It looks like you already go to a club and to a nudist resort, both great places to make friends that could eventually become playmates, so that's great. Your profile is generally good, but please remove any variations on the word "old." You may refer to your age just once, but call yourself "seasoned" rather than older.
Please change your tagline. It's completely appropriate to mention your wife and your status as a widower, but you have done so at the end in a completely appropriate and low key way. Starting with it makes you sound needy and while you might well be very lonely, signs of neediness will be offputting. You also want to eliminate the word "strong" when you refer to the friendships you would like to make, again in the interest of not sounding needy.
You should consider changing your age range to 45 to 70. If a 30 year old was interested, she wouldn't be stopped by being too young and raising the age range will be more comforting for women in their 50s and 60s for some interesting but subtle reasons having to do with the perceived pull dates of middle aged women.
I'm glad you're doing more/different photos. Please take them of you doing interesting things or in front of an interesting background, with a pleasant expression. In the meantime, a selfie of you smiling would be a big improvement.
Here's my harsh but well meant advice: Cut your hair. it is not doing you any favors. You will look much more attractive with short hair in what looks like a lovely silver and you will, as counterintuitive as it sounds, look younger. Start walking, not only because it will give you something to do but because you want to be in decent shape for the rigors of being a third.
My final piece of advice is that, while I don't know how long it has been since your wife died, you probably need to be touched. Get massages while you're waiting to connect with other swingers. It will help you be more settled in your body and you won't be coming from a place of touch deprivation. That last part matters, because women can often feel that need and it's a little scary. If cost is an issue, lots of massage schools offer low cost clinics so that their students can get experience on a wide range of bodies. It's the touch that will help, so you don't need a seasoned practitioner.
