“A desire to engage in sodomy (with a same-sex or opposite-sex partner) is a temptation to sin, which should be resisted.
Actually doing the deed is the sin”
“You have heard that it was said, ‘You shall not commit adultery.’[a] 28 But I tell you that anyone who looks at a woman lustfully has already committed adultery with her in his heart.”
So which is it? Is it “doing the deed” or if a homosexual looks at a boy lustfully is it a sin?
“Looking lustfully” is a sin. Adultery is a sin. Sodomy is a sin.
Nobody intended to say that looking lustfully is wrong for some people and not wrong for some other people. It simply wasn’t the topic of discussion.
There are levels. There is what might be called a sexual disposition: most men and most women are generally disposed to desire the opposite sex, but some are different. These dispositions are morally neutral, although the disposition to desire the same sex is naturally disordered.
Then there is the cultivation and enjoyment of lust, by which we mean a desire to gratify yourself by using another person as an object, without consideration for his or her welfare. That is a sin, regardless of the object.
Then there is actual sexual activity. That is a sin, apart from natural intercourse within marriage.
