What are the spiritual consequences of masturbation? Are there any?

Wondering

There are no spiritual consequences to the practice.

This statement may shock a few; however, we are not puritans. Masturbation is a private matter and is an individual’s business alone, so no guilt need be connected with it.

It is a natural function. Masturbation avoids the risk of venereal diseases and may well forestall sexual unions and unwanted pregnancies. The latter may lead to calamitous outcomes. Lives are often ruined.

So there is no shame in regard to masturbation.
