Hello there. I can understand your concern. It's normal to have a slight curve towards one side be it left or right. No need to worry about it. Nothing will happen. It cannot be said why it is like that but it's for sure that it won't cause any problems in your sex life in the future. Don't be worried. Have a high protein diet and do pelvic floor muscles strengthening exercises daily. Best regards. Dr. Anil Kumar Jain.
