What to do as i am being into regular masterbation for a long time and from the past 1 year or so i am noticing my sperm volume has reduced significantly and now i am panicked and tried to stope masterbation but then after 2 days i got a night fall which never happened with me before and also my left testicles has pain in the upper portion while pressing it a bit. Is there anything anyone can suggest me!!!
Btw i am 21 M
