My 75 year old mother who I live with along with her husband and my father asked me for sex. Her son. She is Baptist raised and this one at least doesn't swear. I say this to show the difference. She is not a holy roller just a normal person in every way. She shows no symptoms other then mild search for a word briefly hear and there and maybe an explanation of something could be done a little better. No one would know anything. She is totally normal except for this. Its to long to go into other then she put her hand on my knee one time after I said something giving a clear intent and then the second time a week later says this softly but emphatically and with exasperation. "You want to f*** hard and I want to f*** hard why shouldn't we just because he is around" I was in shock and just blinked. She just stared back at me exasperated. I have two siblings who could know this as well as my father but I have not told them. Have you heard of this as part of aging?
I suspect that she is not totally normal. Perhaps the trouble finding words and the slight confusion are early mild signs of something going wrong. Propositioning her son is definitely not part of normal aging. Watch carefully for other signs of impaired functioning. Keep a journal of them. Ask your wife to do the same. If a pattern shows up or the signs are more pronounced than you thought once you start looking for them, then I think the next step is a thorough medical exam, with the doctor knowing ahead of time what concerns you have.
Meanwhile, if something like this happens again, I'd say something like, "Mom, I am sure you are a good lover, but that is not a proper activity with a son. It is called incest and it is wrong."
Wow! What a shocker! You must be very confused and worried.
Second I think your Mom may be further along the path of dementia than anyone believes.
Inappropriate comments and a sexual obsession are often a part of dementia. Usually it is men that others complain about but it can affect both sexes. She may or may not have known who she was asking.
She has family around looking out for her and helping so the decline may not be noticeable. Is she actually responsible for anything? Driving, shopping, cooking,paying bills all those kinds of things.
My own mother in law seemed pretty normal too but once her husband died it was only short time till she needed to be placed in a facility. FIL was physically sick but was able to look out for MIL and watch that she did not do anything stupid.
A visit to Mom's PCP would be in order at this time for a complete evaluation.
It's hard to deal with this issue. Relationships with our parents are intimate and deep. My husband, FIL's son, feels angry and hurt and helpless, on my behalf and also because this is his father. We talk, but I try not to burden him too much and when I get really upset, it helps me to talk to a good friend in whom I've confided. You can always come here to talk it out if you wish. People here have helped me through a few rough spots, especially early on.
Do listen to the advice to talk to a doctor. Sometimes this behavior can be helped through medication. But not always. The only medicine that stops my FIL's horny ways are those that put him to sleep. Still, you should talk to the doctor anyway because your mother is showing a sign of dementia.
I know it makes you feel weird, but, I'd try to not think about, even though, it could happen again. Maybe her doctor could prescribe something to decrease her libido.
We just never know what we'll have to deal with in life. Take care.
If it's a sudden change and she's done nothing like it before, report this to her doctor as a neurological symptom. And be as clear and frank about it as you have been here.
