Something very similar happened to me. I was in a serious relationship with a very dom person. He ended up manipulating me and I did not catch on until after he had dominated me. I realized it soon enough not to get married to him but then I had a really hard time even thinking about D/s things. I would get angry just having someone grab my arms during sex or try to hold me down in anyway. I would not be submissive to anyone.
I got married to someone that I love very much but he is not the Dom type. I don't worry about that because it is not something that I have to all the time.
Just recently within the last couple of months I have been thinking about getting back into it. I have a friend that I respect very much and he respects me. After long long conversations we figured out that he wants to be Dom and I want to be Sub. I trust him enough to do this so we have decided that we are going to have that kind of relationship. Just being around him would always make me think about D/s scenarios. Even though at the time, we had not talked about it all.
We have made many many rules about what we can and cannot do and things are starting to get under-way. I am a very Dom person in the other parts of my life and I really just wanted to let go so that someone else could tell me my responsibilities. I enjoy pleasuring men, I always have, so the idea that I could do it and would be expected too was awesome.
So far we are doing a really good job of keeping D/s and "normal" life separate. It seems like we are both level-headed enough people to be adults about the situation and make sure no one gets hurt. He knows about my past experiences and validates that the other person that tried to dominate me was unintelligent, mean and hateful. It makes me feel good that someone else sees it that way as far as the D/s side of things.
I am excited to see what will happen in the future.
