Symtomps of excess mastrubation

for 7 years i have been masturbating regularly. as a result my penis have become soft,my testicles are hanging very low.every time i masturbate my nervous system becomes weak.My cheeks have dropped-in considerably.I'm 21 now. Is it the symptoms of excess masturbation? Should i stop masturbation immediately and stopping immediately results in any side effects?

My dudes hang low too bud dont worrie about it !and somtimes my `friend `doesnt get as hard as it should. Just leave it alone 4 a week or more let it get hard by itself even if it takes weeks.......And the side affects will be a raging boner! A good porn helps too but dont touch it let it grow by its self... or go out and get a great *******$$$$....lol
Ive been trough this too just leave it alone for abit !
