I've never been to Blacks Beach, but I've been to several others, including Gunnison, and at every one I've been to, you see many couples where the man is nude but the woman is not, not even topless. And at a nude beach (unlike most nudist clubs), you are not expected to socialize with other people.
Why don't you persuade your wife into coming with you to Blacks, with the understanding she will have the privacy of a bathing suit at all times, while you are able to enjoy being nude? And it she comes with you, other people will treat you very differently than if you're there nude by yourself. That's been my experience, at least.
Completely agree. I've been a nudist for thirty years, and a real nudist. I am now separated so am a single male for the first time in a long time and wow, how I am apparently viewed with suspicion.. terrible.
