I have a condition/affection called Hypogonadotropic hypogonadism - Kallmann syndrome.
That means that I have a micro (undeveloped) penis, like the one from pre-puberty, and undeveloped 1 testes and quite undeveloped the other one.
In this conditions I can't have a proper family life, including sexual relations, or kids (without a special treatment, being infertile).
I'm doing a treatment with testosterone which is causing me the same effects as in post-pubertal, as sexual drive-sexual desire, urge.
I want to ask if it is a sin to masturbate, to relieve the "tension" from my body, caused by the testosterone treatment and lack of the normal solutions, like a marriage, a thing that, most probably, I will never have.
And if it is, what can/should I do to resolve this? This situation is making me sad.
