hello.. i started masturbation 7 years ago with an average rate of 1 time per day at least. in the first years (say first 5 years) my whole body was ok, i didn't use to make any explosive activities or exercises. but i went to the gym from 20 months ago irregularly. recently i began to feel some pains in several bones and joints of my body.. are those pains related with a 7-years masturbation??
The pains are not related to masturbation. It is a normal and healthy activity.
More likely it is due to your work at the gym.
Make sure you are using the correct techniques, ask a trainer. Remember too, your body does need rest between activities. It's OK to take a day or two off.
