Indeed, a good article. I wish more here would actually not just read it, but cogitate on it a bit before they wet their beds. MO may be lost, but it is because of the media concentration on and twisting of the statement, not because of the statement itself.
I have heard that it is easier for women to become pregnant when they actually get some pleasure out of the experience, so it would stand to reason that having bad timing and being forced would tend to make the body less receptive.
