Definitely not normal. In a healthy family relationship, there is respect for personal privacy. Her behavior crosses the line of normal parental - child interactions. You need to take steps to stop this behavior as soon as possible.
No, it is completely inappropriate. Such topics are private and inappropriate to share with a parent, especially a mother. It violates social and family norms of propriety.
Definitely not. In a family, there should be a proper sense of propriety. Showing something so private and inappropriate to a mother is not only disrespectful but also can cause great discomfort and harm to the family relationship. We should respect the privacy and dignity of family members and maintain a healthy family atmosphere.
This is a very uncomfortable situation. You should talk to her seriously and tell her that her behavior makes you feel violated and uncomfortable. Maybe she doesn't realize how inappropriate her actions are.
This is a rather strange and inappropriate statement. If we assume it's not in a vulgar sense, perhaps it could be a very odd or made - up story about a mother helping with some sort of physical or emotional 'crooked' situation in a very metaphorical way, but the wording is quite off - putting.

Definitely not. This is a very abnormal and inappropriate situation. Family relationships are based on respect and propriety, and this kind of behavior violates basic family values and can cause great harm to family members both psychologically and in terms of family harmony.
