Is it common for covert narcissists to lie about why they avoid sex? My ex wife said she was insecure about sex because her vagina was ugly and that someone joked once to her about an "outie" vagina and that since hers wasn't perfectly formed to the ideal of what a vagina should look like, she felt uncomfortable about sex. Mind you, it wasn't the nicest one around but it certainly wasn't that bad at all during the few times she actually revealed it openly.
Strangely, the only time she really seemed to be in to sex was when we stayed at very expensive hotels. At the start of our relationship she wanted to have sex in public, cars and the beach, which often made me feel uncomfortable.
I also couldn't reconcile her love of extreme hip hop that demeaned women sexually or her admission that she had sex with over 20 men, mostly during drunken nights out,
By the time I got to her she was a classic good girl / covert narcissist with the exception of her strange sexual behaviors.
I also noticed that when she got off sexually it was strange for me. On the rare, and I mean rare occasion that she got on top of me, she would nearly choke me with her elbow and was very rigid, almost like she was riding a vibrator with no regard for the fact that an actual human being was below her.
Very strange signs that I ignored and accepted due to her overall facade of being a great, put together, strong and successful woman.
