I must be playing the game wrong then. I've been playing for almost 50 hours and i've yet to see more than one pair of boobs. I've also encountered plenty of strong fleshed out strong female characters along the way. Triss, Yennefer, Priscilla, Ciri, Keira Metz, Tamara (the Baron's daughter) etc. I also know that there's more to come such as Cerys, Sile and Phillipa.
You were introduced to Yennefer via staring at her naked body for a while. Kiera Metz has her top wide open, and you were introduced to her via her randomly having a bath, boobs out. Ciri has decided that she's too cool for buttons, so her bra pokes through the gap in her top. Tamara is supposed to be a teenager, so it would be weird if she was sexed up. Those are the only ones I've met so far, and so far they have all been Flirty Mcboobpants to different degrees (Tamara notwitchstanding). This is all an opinion, you may think it works, I don't. It's just forced in for me, and takes away from any seriousness of their character.
Now if I was to look at the male characters. The Bloody Baron who is a complex, arsehole of a character which the game makes you feel some way sorry for, no penis flopping required. The commander who told you to kill the griffin (can't remember his name), in the short time you saw him, he was shown as a firm, strong leader who tries the carrot, but is forced to use the stick. You are taken on a rollercoaster of knowing him, first believing him just, to then believing him wicked. The Emperor who clearly has beef with Geralt, but works with him because of what (I think so far) is fatherly love. The gulf between the complexity of male and female characters is striking, to me.
