Blonde or brunette? Who would you rather go to bed with?

Do you also have a favourite type or do you follow the motto "I love all women, blonde or brown" ;) My girlfriend and I could hardly be more different, she has long blonde hair and I'm more the dark type. Which one of us would you rather fuck? Or do you do it like the guy in the video who does it to both of us at the same time because he can't decide :D
