The two Scientologists have spiced up their love lives by learning all about what makes sex mindblowing - and their wives are telling everyone all about their hot men.
Travolta reveals, "You can always learn more about sex and romance and love - it keeps it fresh. You've committed to a person to have sex with and you're free to have as much fun as you like with that person.
"I read books and magazines. Sex is something that's free. It's a personal and physical pleasure, and you exchange that pleasure. If you can't splurge there where can you?
"I like studying sex too. It's not something I do to please my wife. I like the atmosphere too."
