I see nothing wrong with having posters of women, naked or other wise, pinned to the wall. Sure it's tacky and is something that I personally wouldn't do, but it's no different than any other type of poster (such as those of boy bands, cars, animals, national parks, etc...). On the other hand I completely agree that it is rather insensitive of him to keep them up, despite your dislike of them. As far as I'm concerned, the posters fall in the same category as him, for example, hanging out with his ex regardless your protests.
Think of it this way, at least he doesn't have pictures of naked men on his walls.
