I had the same feeling when reading the books, a couple of chapters in, and I was thinking misoginistic shite. However, I stuck with it, and realised that Martin is deliberately setting up a hugely misoginistic society, but placing strong female characters within it, many of whom are fighting against these expectations. None of these characters are without flaws, but you have Cercei, hungry for power denied to her by her gender, and seeking to grab it by what ever means possible. Arya, born into the society with certain expectations on her, which she has never fitted into, and finds her circumstances allow her to break away from those expectations. Brienne, who doesn't meet the expectations of femininity either, so takes on the role of a man, but has to fight all the way to be taken seriously. I could go on, with daenarys, Caitlin, ygritte, sansa, margary etc. actually the female characters are often the strongest, best written characters on whom the plot often revolves.
How well the TV series manages to show this is not always clear, however I think that what they are doing is trying to show the violently sexist society of the books, whilst trying to make it more palatable to watch, hence giggling naked prostitutes rather than some of the more gruesome sexual violence and language from the books. It's noticeable that they have also adjusted the ages of the younger characters too, to make it more watchable, as some of the characters such as Daenarys are sexually active at very young ages, as they would have been in a medieval society, but showing this would be outrageous in modern times.
