Without the Torah there would be no reason homosexuality would be prohibited. In the ancient world this perversion was quite common, so much so that the women of Egypt were mostly homosexual and so too Potiphar (who purchased Joseph) was an Egyptian homosexual.
I personally think it is disgusting but I think a lot of things are disgusting and don't try to force others to be disgusted by those things. But homosexuality involves two human emotions which HaSatan is very adept at manipulating, these are sexual pleasure and the feeling of loving and being loved. The maxim 'If it feels good, do it' fits the homosexuals lifestyle choice. Even if doing the act causes shame and bad feelings, they will continue to do the forbidden act as long as 'it feels good' and they feel 'loved'.
But this is the Satan (Evil Inclination of man) speaking to them. Their relationships have no merit in the world to come. Their acts require their neshamahs to have to go through prolonged exile in Gehinnom to remove the blemish of their abominable acts.
