Okay sweeties, here´s what my dad would say: better to apologize than to ask for someone´s permission. So I´d just have taken down the posters without asking, and then I´d have told him very politely (if he said something about it) that while I am there, I won´t accept looking at naked women. If he´d get angry, I´d just tell him to call me if he wants to see me without other naked women around and then leave silently.
The thing is to do this with your head very high, without doubts and of course with no fear of loosing him. See, sometimes guys are like horses or like those big dogs you have to teach who´s boss. If you are very certain of what you will and will not accept in a boyfriend, he will notice it and won´t try to talk you out of it (at least not for long). He will even respect you for it (there´s always this respect thing with guys, even when they´re older and supposedly more mature - you ALWAYS have to make yourself be respected, no matter how nice he seems).

If you do complain about the posters, but still hang out in his house, you´re telling him this:
- you don´t like it, it hurts you but you´re willing to put up with it for his sake
which means:
- you will stick with him even when he´s being an ass, so he can ultimately get away with a lot more.

Another thing is that talking never really works with guys, only your actions will make them change their behaviour. Like if you continue going to his place and complain about the posters (or make faces at them, which is just a sort of silent complaint), he´ll just be annoyed. But if you refuse to hang out in his house from now on, he´ll get the message.
Don´t worry about your boyfriend being inmature, ultimately we have to teach everyone how we want to be treated - also the "mature" boyfriends!
Well, that´s just my 2 cents. Hope it helps some.

Well put girl!!!!!!!!! You wrote what I was thinking but I couldnt put it into words..
