Can you learn to be passionate about someone if there's no chemistry at first?

If a couple like each other, have fun together, and basically have a good relationship, they shouldn't call it quits if everything is there but the sex. Chemistry can grow if you give yourself permission to learn about yourself as a sexual human being and to communicate your desires. That's probably better than falling for someone in a mad, passionate heat. Because when you realize you don't actually like each other, sex is the first thing to go. And then you have nothing. — Sue Johanson, RN, host of Oxygen's Talk Sex with Sue Johanson and author of Sex, Sex, and More Sex (Regan)
