Ok im gonna break this down on why it’s wrong
So im catholic and can just say gay sex is wrong sex is only moral when two ends are met one that it may create human life and two when it brings one man and one woman closer in the covenant of marriage being that they are not married and not one man and one woman this clearly breaks this rule being that no woman is involved means that no child can be conserved therefore it is wrong by breaking both rules
As long as the brothers are enjoying each other, They should continue to have sex as much as they want and need.
This is not about some silly moral argument, This is about maturity of anyone who accepts that in the society we live in there are many who accept gay incest. All of them deserve our support and acceptance.
