Gender Discrimination?

So I've been wondering about this for a while now. I'm currently applying for jobs after the 2nd company I've worked for in the past 2 years was acquired (FUN). I've made it to the final round multiple times, and the panel interviews consisted of 90% women (in fact pretty much 90% of all interviews for all jobs have been women). So these are entire teams of technical writers comprised solely of women, and in each case the person who got the job over me was another woman but with far less experience than I have. Like 1-4 years vs. 10+ years for me.

Am I crazy or is technical writing a girl's club? Is my experience novel, or have other men in technical writing experienced this as well? I'm extremely frustrated with the market right now.
