I'll address it..."Is it common for women who are in healthy, active, normal sexual relationships to not want to have their partner touch their "private parts", such as their breasts and vulva?"
No, its not that common for women in healthy, active, normal sex lives to not want to be touched...although some women who are healthy, active and normally sexual will still not prefer to be touched directly...however normally this points directly to some kind of trauma having happened to the woman. Ie: your wife is normal for a woman who was sexually abused as a child (she is not in a normal sex life because of this, regardless of your marriage). Some abuse survivors get over this and come to have a normal sex life, including wanting to be touched in those areas.
Keep in mind though, that there are men who don't want to be touched either. Everyone is different and has different tastes. Some men want to hop on and hop off with no touching or intimacy.
