I'm middle aged and used to attract plenty of attention from some. I'm fit and exercised extensively pre Covid, and compared to many of my peers, I stand out based on my fitness level. Plus, I'm around 6' 3" tall. On a grading scale from school of A through F......I would say most would grade me as B+ , while in my younger years through early middle age.
However, many would immediately lower my grade to F, because I shave my head due to male pattern baldness.
Plus, the last six years, I've aged a lot. For many of us who have entered our fifties, it seems the aging process really accelerates in late middle age, and it has in my case. I'm definitely turning substantially less heads than when I was younger. I accept this reality for myself.
My outlook is this for myself - between all the visual and intrinsic short comings (my personality is extremely quirky) that I posses that I might turn off 90% of the opposite sex, at this stage in my life, but I'm not looking to attract 100% of the opposite sex; I'm monogamous and I only need to attract the one person meant for me. I take this process as "finding a needle in a haystack".
