When we are born, we come into this world with an agenda of lessons that remain with us until we have chosen to become their master. When you see conflicts/problems/people with the same kinds of problems, pay attention to them. Even though the people, places and events may be different, the battles are always about the same thing. These related conflicts are unlearned lessons from the Universe and until realized, will continue to be a source of trouble for you. As each person is unique, so too are the lessons.
What is a lesson? A lesson is a task and/or exercise that a student discovers and practices within a given time period. Spiritual lessons are also assignments; call it literal homework that deals with ideas, actions, and behaviors. And like the basic definition of a lesson, a spiritual lesson has a given time period in which to attain-our lifetime.
Take some time, meditate and figure out what lesson you need to learn regarding these situations. Sexual problems stem from lack of control, wanting control and not having it or fear of taking control of your life. Where in your life do you feel out of control? Take charge of your life, learn the lesson and your life will become manageable.
Don't forget that you are not alone in this. Ask for heavenly help from your Higher Power and especially from your angels. You are courageous and powerful! You can do this! I am sending you lots of love and positive energy for your journey.
