As a young gay man in my 20s, I had some concerns about getting older.
I was never concerned about getting sick or dying prematurely.
What were my concerns?
I was a bit afraid that I'd be lonely.
I was sure that no one would want to fuck me beyond a certain age.
I thought that I'd look pathetic going out to clubs as an older gay man.
I was terrified that I'd lose my ability to get hard.
I was never worried about how younger guys will treat me when I get older. It was never a concern because I'm such a nice guy. I never treated anyone differently, just because they were older than me.
I do find most older guys unattractive. That's not because of their age, lack of hair, white pubic hair, or wrinkles.
