So being a Catholic Teenager it’s let’s say pretty difficult to maintain a pure life free from impure thoughts and that. For the most part I have and have warded off the evils of pornography and lust. Though I’m currently confused on this issue about masturbation. I’ve been doing research into seeing is it a sin or not (I’ve been told it is a sin and have upheld that it is) however certain websites that are fairly legitimate have been saying that the act of masturbation is not a sin and that it’s only the thoughts that come with it. It goes on to elaborate that if one can block out impure thoughts then masturbation isn’t really a sin. Is this true? I’m a bit confused at this so please help.
