The hardest part was forgiving myslef for being helpless...
My first boyfriend abused me sexually during our relationship. It all started out nicely, we were each others first times, we got along and the sex was nice. As time went on he became more and more aggressive towards me. He would do things to me that would hurt a lot. I tried stopping him, I told him that it hurt, I begged him to stop... that would only turn him on more... He even harassed me with a miniature baseball-bat because he said I was "too tight" and needed to be "loosened up". I was till young, I thought that you can not be raped by someone who you are in a relationship with. Never have I been so wrong! I haven't told anyone because I was afraid no one would believe me, he was quite popular and well liked. Needless to say, I broke up with him. This happened about five years ago... I had moments during sex afterwards, when some minor thing would go wrong, a slip of the hand, a slight pinch, anything remotely unpleasant, I would freeze up, my body would get numb and I would start crying. I guess I am still recovering.
Counselling will help speed the recover along.
My second gf was abused by someone she was dating and had the same thing where she would freeze up when something went a little wrong. Over time it got to be less and less, you just have to work through it with someone patient.
