I wouldn't rule out parental abuse, but it might not be sexual. I could see where an overbearing parent might have tried to instill gender-role behaviors so deeply that acting outside of traditional behaviors would terrify him, but it's time to grow up.
I'd love to know why our KiMare is so convinced that parental gender matters so much. Given that parents aren't supposed to be engaging in sexual relations with children, any children, but especially their own, I can't figure out why he/she is so fixated on it.
The only thing I can come up with is that maybe the sex he/she had with his/her parents when he/she was growing up was so good that he/she thinks that all children should engage in regular sexual relations with their parents.
As sick and demented as that notion is, I can't figure out any other reason why he/she would find it so critical and, given the level of crazy with his/her other posts, it does fit well with the rest of the crazy, doesn't it?
