As I mentioned, and I think others have as well in other threads, this seems more like a USA thing. And I would say some of them were comfortable telling me the truth as some of them in college I was dating. In the work place I never dated any, but was close friends with some and never heard a complain. Actually, thinking about it, while the ratio is skewed in the programming front, where I worked, there was a tendency (albeit small) for women to be more represented in higher level positions. Heck, I just accepted a job leading a team at a startup where all programmers are men, but both C level executive are women.
