First sentence:

Some time ago, one of the male authors was chatting with a very attractive girl he had not met before. While he was anxious to make a good impression, when she asked him where he lived, he suddenly could not remember his street address.

It's interesting that women aren't similarly affected by mixed-sex interactions. Coed education disadvantages men?

Aren't they? I've seen plenty of women get tongue tied around men they're attracted to.

It's likely a matter of it being socially acceptable for a woman to smile nervously and stare at the floor during courtship, so losing one's cool is a problem from a man's perspective, but is all part of the experience from a woman's.

Not according to the study.

  >> Coed education disadvantages men?

There is some evidence that coed education can be detrimental to both men and women. http://www.singlesexschools.org/research-singlesexvscoed.htm

It has been suggested that some women fall behind in math in high school due to a desire to not appear too smart.

It's a long-running hot potato in education. The studies seem to swing all over the place (as do the attitudes of schools willing to "experiment" with the topic). A high level hop around the subject: http://www.guardian.co.uk/uk/2006/jun/25/schools.gender2
