Actually, this is not correct. These two "consenting adults" engaging in sodomy are harming themselves. And the harm is both physical and spiritual. The physical harm is evident in another thread on UF that Abu Mubarak maintained, I would have to search for it.

The spiritual harm is more than just "religious", it alters the self, one desires filth and impurity and resents and despises purity, modesty, virtue. This is why homosexuals have one of the highest suicide rates, because they are conscious of their own degradation and defilement, their own desire for impurity, and despise themselves for it.
