is masturbation a sin for a christian?

Answer 1

Yes but I do my own thing!

Answer 2

Yes. The Catholic Church is the only Church founded by Jesus 2,000 years ago. The Bible tells us that Jesus gave all of His authority to His Church to teach until He returns in glory to judge the living and the dead.

For more on why the Catholic Church is the same Church that Jesus founded try reading this article which tells of the 4 marks of the true Church founded by Jesus:

Here is the official teaching of the Catholic Church on the subject:

Offenses against chastity

2351 Lust is disordered desire for or inordinate enjoyment of sexual pleasure. Sexual pleasure is morally disordered when sought for itself, isolated from its procreative and unitive purposes.

2352 By masturbation is to be understood the deliberate stimulation of the genital organs in order to derive sexual pleasure. "Both the Magisterium of the Church, in the course of a constant tradition, and the moral sense of the faithful have been in no doubt and have firmly maintained that masturbation is an intrinsically and gravely disordered action." "The deliberate use of the sexual faculty, for whatever reason, outside of marriage is essentially contrary to its purpose." For here sexual pleasure is sought outside of "the sexual relationship which is demanded by the moral order and in which the total meaning of mutual self-giving and human procreation in the context of true love is achieved."
To form an equitable judgment about the subjects' moral responsibility and to guide pastoral action, one must take into account the affective immaturity, force of acquired habit, conditions of anxiety, or other psychological or social factors that lessen or even extenuate moral culpability.

Answer 3

no.
