Libby: Here is the beauty of the situation, Bram. It's not up to you whether I stay or go. The days of me organizing my life around a man are over.
Keller: Then I'll organize my life around yours, unless you can stand there and honestly tell me you don't love me.
Libby: I'd say all the evidence points to my loving you.
Keller: Then the defense rests. For the time being only, you go, and do what you need to do. But one day, you will look up from your disgusting tempeh burger, and I will be there... a man who has upended his whole life for you.

I think women often confuse love with physical attraction.

Dr. William Masters, he's the alpha dog of coochie medicine.

Jane

What does a blow job mean? What are you a girl?

William [to Ethan]

I simply want to answer the question what happens to the body during sex.

William

Dr. Haas is not the best fertility doctor in the Midwest. I am. Shouldn't my wife have the very best?

William

Maybe in a strange way it's romantic, the two of us together, making a baby through science.

Libby

If you were having a contest for most sexually adventurous girl in the hospital, who would win?

Ethan

I'm asking if you like to watch, because if you do, you can watch me.

Libby

This is either the smartest or stupidest thing I've ever done.

Virginia

You humans have taken the basic impulse for sex and turned it into some unrecognizable ordeal. Romance, chivalry, codes of etiquette.

I'm not on the menu.
