But like you, I'm a "46" who loves younger women.  And thank god I'm young enough to still enjoy them.  I had some great fun with a 22-year-old, then took her to dinner at a high-end steak house with friends (another monger and his hooker date, who's also a buddy of mine) and was prepared for some old biddy to walk up and wag her finger at me, saying, "Shame on you!  She's young enough to be your daughter!"  My reply would have been, "Oh, no, madam! She is far too young to be my daughter!"
And that would have been true.
Life is good.

I've mainly had my gentleman friends of a more distinguished age humorously refer....

...to themselves as dirty old men during a date like a badge of honor lol.

I first remember it from Arte Johnson on Laugh In. But I suppose it was already a cliché that he was exploiting.

My SO constantly uses that term when referring to me. As far as I'm concerned I worked hard to get that title and I try my best to live up to it!

D.O.M.

I intend to be a dirty old man until I'm a dead old man. 8o)

I accomplished the dirty part many decades ago and now the old part is coming along nicely, thank you very much!

An old man checking out teenage girls in the park, while he sits with a newspaper in his lap. I think you can get the picture.

More common is a good old fashion lech, hitting on young women. My daughter, 24, was laughing about a "Dirty Old Man" who tried to hit on her and a friend. "Ewe dad and he was even older then you." She will never know that was the day I left her out of the will
