I agree with Thunder Bow in saying it is a dream of healing. Your early sexual experience with a male "somewhat authority" figure, your father, was traumatic. In this dream you have a sexual experience with a man that feels pleasureful. Also Mike was suicidal and you entered his life and provided healing for him, so you have this nurturing and healing capacity in you. Think about the possibility that Mike in the dream is a part of yourself, the "man within the woman" (I'm assuming you are a woman) (the qualities in yourself that you associate more with men than with women), who is initially ill, but you provide healing to him.
