I do not know what the Catholic church teaching is on this
With all due respect, I would like to remind you that this is a Catholic website. Before you give advice to Catholics, please do your best to at least learn and understand the Catholic position. Do not give advice that is contrary to what the Catholic faith teaches. Your intentions may have been sincere, but you have just encouraged a young man to commit a mortal sin. Masturbation is still a mortal sin even if you choose to ignore this fact.
That being said, here is what the Catholic Church teaches concerning masturbation:
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."137 “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."138
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, if not even reduce to a minimum, moral culpability.

Since you are a protestant, I would also like to add that many protestant denominations consider masturbation to be a sin. Although some denominations do not consider masturbation to be sinful, all denominations acknowledge that lust is a sin. Since it is very unlikely that you will be able to masturbate without fantasising about sex, you are also guilty of the sin of lust even if you do not think the act of masturbation is sinful. If I were you, I would seriously question your views on this subject.
