"Uh-oh! BEWARE!!!" said Fensler. "Never, ever marry the best sex of your life. It only happens with someone who is very dangerous for you. It's passionate, exciting, but it generally indicates that you are pushing each other's dysfunctional buttons. Be very wary of men you are crazily sexually attracted to-they're the dangerous ones for you. That's what all analysis says in one form or another."
