I need some un-judgemental advice.

I am worried my marriage might be in trouble. I'm not sure if this is one of those seasons a marriage goes through or not, but I've been married 6 years and this is the first time I've felt like this. Lately I don't want my husband touching me at all and everything he does annoys me. I still love him dearly, but I'm finding I have to force myself to get in the mood and sometimes just detatch myself completely during sex. We've had quite a few stressers pop up in the past two months, and I'm hoping that is all it is, but I'm concerned it isn't. He keeps pushing for more sex and it turns me off and I feel disgusted with the thought of it. I've had past sexual trauma, and this feels almost like what I felt like after it happened...I don't know. I love him and can't picture anyone else who could take his place, but I just feel grossed out by any physical contact. Am I broken? Any advice?
