As Christine said work on emotional too.
Self esteem, insecurities, image of self, confidence and mostly sexual repression or misuse.

Since you're doing energy work have you done reiki?
That can help you clear emotional from childhood and even past lives.

Try intending for your sacral to be balanced and flowing and hold both hands on it. Or one on heart and other on sacral.

Pay close attention to the thoughts and images that cross your mind while doing this. Don't judge or fight them. Just focus on being grateful for your sacral opening up and breathing. These thoughts colors or feelings usually indicate what and where it's stemming from. find a reiki practitioner they can guide you through this process very well. Not to mention treating the blockage but finding the sources may help keep it clear.
