R90, you are most certainly correct and reminded me of a true story from a friend and fuck buddy of mine.
My handsome hung friend, in his early 30s at the time, was at an upscale private party and was approached by an attractive gentleman. They retired to a bedroom where my friend fucked his brains out -- was shocked to learn that the man was aged 62!
R91, you're very wise to point that out. I grew up in what was a small town, but what is now a thriving metropolis. Moved away before things like manhunt and grindr came along, though. My gay best friend wouldn't "hook up" for the very reason you mentioned, and cautioned me since I had career & political aspirations as a young man. I have an online married buddy in the same situation with two teenage sons. It's bound to happen sooner or later.
The silliness about people of education & accomplishment not posting profiles with nude pictures on the internet is pure bullshit!
When I was sexually active, bi & married men were attracted to me because I'm naturally a private, reserved person who doesn't "kiss and tell." Through the internet, I met other educated, professional men from all walks of life of accomplishment including aerospace, engineering, law enforcement, & post-secondary education.
Wasn't the case of the right-wing sheriff in AZ who had an illegal alien boyfriend AND an X-rated adam4adam profile previously discussed on DL?
I don't know what to think of the OP's story and if it's genuine. My father died an early death when I was 19, but I never saw him naked.
If I'd seen my father naked and knew he was gay & single, I wouldn't be shocked to see his ad on manhunt and that he's a top. Better than him being a sloppy bottom like most on that site...
"So son, you like big dick and getting your asshole punished like most gays, doncha? I'm so glad I came out... I'm just having a great time ruining one ass after another!"
