Without wanting to pick a side in the sexism war, I had exactly the same impression regarding Andre Norton and whilst I have read thousands of SF books I cannot remember enjoying anything by female authors.
To put it bluntly, only male authors are likely to write something autistic enough with which I can identify. Female authors insist on including relationship crap.
That's fine in regular fiction, but in sci-fi I want spaceships and mayhem.
Whilst I'm on my soapbox, it bugs the hell out of me that when even one of my favourite authors, e.g. Iain M Banks introduces a main character who is female, she is invariably stunningly attractive. Why can't she be just someone ok looking, but a good laugh and handy in a space bar brawl?
