Dear
Welcome to HCM
We understand your concerns
I went through your details.
Masturbation is a natural process and it cannot affect your heart, intestines, brain, vision,
urinary bladder, lungs etc. Masturbation in moderation cannot have any adverse health problems in you directly. Indirectly, if you be anxious about it, if you become worried about it, without proper knowledge, relying on absurd information, masturbation practice and related worries could lead to
anxiety disorder and anxiety disorder could, in turn, lead to
erectile dysfunction or
premature ejaculation etc. Keep yourself away from wrong information and resultant obsession.

Good luck.
