" If you put sexual attraction on a scale of one to ten, where ten equals "you can't keep your hands off each other,"five equals "you can take it or leave it," and one equals "repulsed," to support a vibrant relationship, it should be at least a seven, preferably an eight, nine, or ten. With work, you might raise the attraction one notch, but because there is so much biochemistry involved in sexual attraction, it's hard to do much more than that. So if a sexual attraction doesn't evolve, remember, it's not anyone's fault and it's just the what is of your pairing, and you might make better friends than lovers.

Sexual attraction doesn't have to be instantaneous on first meeting, but it must eventually flower because it provides a basic glue for successful conjugal union. If we're not sexually alive to our beloved, it often leads to a subdued relationship, loneliness, affairs, or lots of fantasies. "
