Hi. I'm going to second everything PAW has already said, including the disclaimer about the intent of those responding to your request for feedback. And I'm going to pretend that I haven't read her critique, because sometimes the weight of multiple people saying similar things is what's needed to make an impression.
So, first, the use of a half naked bathroom selfie, while it might seem like the answer to a prayer, is not only an unappealing cliche, it's ineffective if one's aim is to attract women. Unless you have Duane Johnson's body before he lost his neck somewhere. Otherwise, please put some clothes on.
Moving on to your age range, we like what we like, but swinging is a really interesting subculture in the way it turns one particular norm on its head. Because single men of all ages are the largest group, which provides a lot of choices, it's not unusual for women who play with singles to develop a preference for playmates who are 10-30 years their junior. At the age of 50, setting your age preference at half your age to five years older will not only have women everywhere rolling their eyes, it will materially affect your ability to find playmates because you're too old for many women in their 40s to 50s. I mean, you aren't really too old, but you're effectively competing with men half your age and there are practical reasons for women to have a preference for younger playmates.
Taglines should be an invitation to take a peek at the profile. So, short and clever is best, but short and sincere is fine too. Just not explanatory, please, the way your current tagline reads.
The rest of your profile suffers some in that you appear to be looking for people who can serve your needs. Your need for exploration, for friendship during your travels, as dates to clubs, for someone to bring you out of your shell. Like, sure, of course those things would be lovely, but you won't go far in this unless you turn it around and focus on what you can give. There is a common 'single men are a dime a dozen' feeling underpinning the way many couples view your group. I don't agree, because I think everyone is unique and valuable, but the demographic realities - there are a lot of single men on line, very few single women, and perhaps only half of all couples looking for single men - means there are a lot of your group to choose from and success means having something to offer.
Really, unless there is something specific that draws you to the lifestyle, you're better off with Tinder, where the odds aren't so far against you.
