Sex advice PLEASE!!! How do you ignite your 10 year relationship?

My spouse and I have been together since 2012 (10 years together!!!) We are both 25 years old, high school sweethearts and have a 14 month old together.

Our sex life is a disaster. It's been a disaster since 2018 and it's getting to the point we are both VERY frustrated and I feel it's all my fault.

In 2017 I was sexually assaulted and ever since it has been extremely difficult for me to look at sex the same way. My spouse has been very understanding with me ever since and has never tried to push me to do something I never want to do. However, we have spoken multiple times how his sexual desires are never met and I can't even get aroused. We probably have sex like once every 3 months. Before it was 1 time a month, then our son was born and now it's once every 3 months. To be honest we've only had sex like 4 times after my son's birth, so probably less than every 3 months. The point is: our sex life is a disaster!

I can't get aroused. I want to get arouse. I want to feel sexy again. I want to make him happy but my body just rejects any kind of physical touch!!! I feel so fucking useless and my poor husband is sexually frustrated because his libido is so high and mine is non-existent. He masturbates a lot and I don't care because I can't satisfy him.

But here's the thing: I'm okay with touching myself. Im okay with idea of sex as long as I'm not being touched.

I feel like a failure of a wife for not wanting or liking sex anymore.

I don't find myself sexy, my baby weight and stretch marks are unappealing, and physical touch makes me cringe so hard now! I swear I feel we might get divorced because of this and I don't want to lose him.

I want to get that fire again! I want to reclaim my body as mine and sexy and be thankful for it. I want to feel sexually attracted to him (I love him to death! It's the sex that's for me!). I want to have sex without cringing, or being squirmy for feeling ticklish because my body fights back any kind of touch. I want to accept touch again but I have no idea how to go about this! Every time I try my husband wants more and I can't give it to him 😭

Any advice? Am I crazy? Is this fixable? Am I a lost cause? 😔
