physical attraction

I never felt much of a physical attraction for anyone else.

There had never been anything more than physical attraction between them.

There is a lot of physical attraction between them, but they don't really like each other.

So I guess physical attraction is at the bottom of it, and always will be.

When you are up high, there is a physical attraction to the empty space below.

He had never before experienced such a powerful physical attraction toward a woman.

In the past their relationship had been shaped by physical attraction.

Had she spent over thirty years not understanding what physical attraction was?

To be sure, like many a rock star these birds do not offer much else in the way of physical attractions.

Perhaps it had been the physical attraction he'd felt even though she was exactly the kind of woman he avoided.
