My wife is a teacher. Several guys in the office are married to teachers as well, and most of my friends in college were dating ed majors. I think this happens because engineering is primarily male enrollment, and education is primarily female enrollment, so we just naturally blend together.
Interesting - I am a female engineer who was married to a male english teacher. Sadly, we have been divorced now for about as long as we were married (8 years). I think he had a difficult time with my wage compared to his, and because I worked much longer hours than him, I was unable to prepare dinner for him on a regular, timely basis.
