No, its a myth. There are many myths about masturbation. Even though many of these have been debunked several times, they seem to resurface time and time again. Most claims about masturbation are not backed up by science. There is often no scientific evidence to show that masturbation causes any of the adverse effects suggested. Masturbating won't make you blind, crazy, or stupid. It won’t damage your genitals, cause pimples
, or stunt your growth. Masturbation will not cause:
impotence later in life
low sperm count
some couples worry that their relationship must be unsatisfying if either one of them masturbates; this, too, is a myth.
