Was this covert sexual abuse?

I know my mother was emotionally abusive but after reading an article on covert sexual abuse I'm wondering whether this is something she also did? I've had my suspicions for many years but dismissed it as me being overly sensitive.
She was frequently naked around me even when I got older and encouraged me to be 'free' also saying it was funny and natural.
She told me sexual things as a child/teenager such as the time a friend of her mothers put his penis in her hand. She would often repeat this story.
In order to alienate me from my father she told me the sexual requests he made of her such as to start swinging, that he said anything sexual was ok, which she took to mean even children, that she was frequently raped by him as she was too scared to say no, that I told her as a small child I saw his penis in the park (which I have no memory of), that he and all men were sexually screwed up so that's why she became celibate. My father never abused me and I'm convinced of this, I have a great relationship with him.
That her first husband was gay and having an affair with his best friend and that his sister was abusing him.
I felt 'sick' when I had to hug her and avoided it as much as possible. I became very OCD about sexual abuse (not surprising really) and was paranoid she was trying to touch me or even 'breathe' on my body parts. I don't think she did touch me but the fear was a 'what if' fear.
Unfortunately my first sexual experience was rape from a 'friend' and I developed vulvodynia (vulva pain) and vaginismus (involuntary tensing of pelvic floor muscles making penetration painful) but I believe these conditions are also rooted in my childhood and the things my mother was saying to me about sex.
Thank you for reading

You may want to speak to a professional about this before you decide on a label. It is clear that your mom was causing a lot of distress, but "covert sexual abuse" seems an inadequate description, even if her behavior was suggestive or made you uncomfortable with sexuality.

Whatever you label it, none if it was ok. It is an unfair world when we must strive to be healthy despite our parents, instead of because of them. I cannot be much help but I wanted to give you my support. Best wishes to you as you figure this out!

I'm not sure what you want to call it, but it was extremely inapropriate for sure and it wasn't good for you for sure as well. And I feel very sorry for you about it.

I believe that question if it was abuse and if so, which kind of abuse depends on the question what the intention of the abuser is and which desire is fulfilled by the actions.

My late grandfather told his daughter(my mother) on the phone that at the age of 80+ he was still having erections, but that he hadn't touched my grandmother since decades as he was disgusted by her and he would need another woman, etc.

Now, having known him very well, I know this was clearly abuse. But not sexual abuse. This was about his unsatiable desire for being admired. But to get admiration and confirmation how great he was, he needed another person. But whom should he have told it? Any friend, neighbor or same generation family would have scorned him for saying so. Or at least they would have at least shown their embarassement and disgust, so it wouldn't have worked. But he just had to tell someone. So he chose his own daughter to do so. And that's the abuse.

You know, there is this an old joke. I hope you allow me to quote it and I hope you are not offended.

A young man goes to a catholic chuch to confess. When the priest asks him what sin he had committed, the young man says "Last night I did it to my wife 17 times straight" to which the priest replies "Well, this might be a bit unsusal, but since you are married, it is not a sin". To which the young man says "I know, father, but I just *had* to tell somebody about it".

So, just a sick joke, but as a matter of fact this man ab-used this priest for his desire of bragging. And this is what my grandfather did to my mother. Same story.

My recommendation for you would be to ask which desire your mother tried to fulfil by doing this to you. From what you describe it could be the desire for excuse and justification why all her relationships had failed. Friends, neighbors, etc. might have contradicted her, might not have believed her and said so and even asked her to stop talking like this and would have turned their back on her if she didn't. But you couldn't walk away and couldn't have contradicted her. This is what makes it abuse to me. But of course I could be wrong about this.
