Hi there ~
I understand your concern, however your issue with masturbation
is a non-issue. Masturbation is a normal physiological process, however it can cause problems when done in excess. I also feel like you need to see a doctor to have yourself checked out for the back pain
since it seems to be the cause of most of your issues. I also feel that fatigue
is related to the back pain, however you need to be examined by a doctor to give you a proper diagnosis and the right treatment. I hope this helps. Take care and have a lovely day!
