"I screw, I sleep with, I make love with many men and not one of them has said, 'I want you for my life'," she said.
Now, she only dates men years younger to keep herself happy.
During her time using several match-making apps, Retroage has found a selection of casual lovers she has matched with, revealing he had met close to 50 men in eight months.
Her Tinder bio reads: "Hattie, 83, fascinating older beauty. Seeking a steady younger friend/lover for a shared life of adventure and passion. No pro-Trump and no players."
The youngest man she has been with was 18, although she believes he was older and lied about his age.
Retroage is currently dating Shaun, 33, a 50 years age difference.
"I'm not agonising," she said. "I'm grateful that at this age and this stage that I have as many lovers as I want.
"My life goal is to change the awful, decrepit view of ageing – view and experience, and turn it into something exciting. A life-loving adventure.
"The depth of life, you can't avoid it. But the shallowness of good sex, that's what is good enough for me."
Hattie said that she is often referred to as a "cougar" but is trying to reverse the negative preconceptions attached to the lifestyle.
