Which country do you assume OP is in? In Germany women only make up 16% of engineers http://www.zeit.de/2013/38/frauenanteil-ingenieure. In my starting class of 300 ten years ago there were 5 women in electrical and computer engineering. Mech and building engineering was much higher. Computer science was somewhat in between. In my high school some girls went for math and many for medicine (still a science, somewhat), but none went for engineering or computer science AFAIK.

I think you're too easily discounting his personal experience. If you ask me, at least in Germany, EE and CS is pretty much devoid of women. And if you're talking about dating, a small pool of women surrounded by men will probably be off the market most of the time. So him never dating engineers at least in my experience, is the norm.

They're doing a lot here to attract girls to STEM, but it isn't bearing much fruit.
