Intimacy is not sex. It is emotional closeness, and without it, sex is just sex. I've heard many survivors who complain about a lack of intimacy. Intimacy and love take two. Be considerate of your partner's needs and they will be more open to yours.
Mutual satisfaction is the goal.
By sharing your needs, you will slowly gain a sense of confidence and trust. I can't begin to speak to all of the issues concerning trust, intimacy and sex. I can only say, that if you are having problems in your relationships that are related to your abuse, you are not alone. I'm betting that a big percentage of those women are survivors. If you need help, and your relationship is important to you, think about seeing an experienced counselor.
