Self-Gratification Is Still a Sin

Actually, there is no new Church teaching on masturbation.

The Church has always definitively taught that masturbation is “an intrinsically and gravely disordered action” (CCC 2352). It is a corollary teaching of the sixth commandment. And when committed with full knowledge and complete consent (CCC 1859), it is a mortal sin (CCC 1854-64).
