I'm just going to point out, for those in the thread and lurking, that what Le Gra Go Deo originally posted was gender stereotypical, and goes hand in hand with what sexist biological determinists think. Men are more emotionally needy, and women have sex for "a sense of well-being, acceptance, confidence, bonding" etc. as well.
@Big Mama- I'm sorry that you're going through a hard time with this. I think that your husband needs to open his mind to the fact that you don't exist for his sexual gratification, that him manipulating you and pushing you to be sexual is wrong, and that you taking a step back really is not about him. The way I see it, he has hands that he can use. He needs to respect you and your decision to take your time to heal and process what you have been through.
I hope he can take the initiative to do some research so he can begin to understand what you've been through and the reasons you have for not being sexual.
I had a similar issue with my last partner and I had to end it because I couldn't be with someone who didn't accept that part of me. My mom is also having similar issues like yours, and she has to talk to my dad about it every so often when her ptsd gets bad.
This is your time to heal, and to find the strength within yourself, and I believe that you can do it. I send positive thoughts your way
