Kyle Jones, 31, dates numerous pensioners at a time and can't keep his hands off of Marjorie McCool who he has slept with for more than five years.
Ms McCool, who has a 60-year age gap with Mr Jones, likes to wear "sexy outfits" in the bedroom and describes their sex life as "wonderful".
The pair are involved in a casual relationship and Mr Jones uses dating websites to find older women and chats up other pensioners daily.
Mr Jones, who lives in Pittsburgh, Pennsylvania, said: "Everyone's brain is wired differently, some guys prefer blondes, some brunettes, some like other guys - I like old ladies."
