I just watched "War of the Roses" (Good Movie!) so I'm going to use it as an example. Michael Douglas is 10 years older than Kathleen Turner in real life, about the same difference as Donna and Terry, yet they were paired together romantically in 4 projects. Michael Douglas is 25 years older than Catherine Zeta-Jones, yet they've been happily married 22 years. If you're compatable after the age of consent age is just a number.
