If one breaks down the verse you are trying to refer to word for word, from the Biblical Hebrew one discovers it does not say what you so desperately wish it says.
First of all, lo tishcav, "do not lie" comes from the word for lie down as in 'lie on the bed' or 'lie on the ground.' Other condemnation of sexual intercourse or sexual activity in Leviticus did not use 'do not lie' rather Rather the author wrote "do not have carnal relations with" or "do not uncover the nakedness of" to condemn sexual activity.
Why would Leviticus include this verse if it means only that to lie beside a man is obscene? Furthermore what does obscene mean? One definition for obscene is, "designed to incite to lust or depravity." Thus, we can conclude that a man should not lie with a man because it may incite lust. But so what? The bible doesn't have issues with lust, in fact, the Bible records several stories of passion and mutually enjoyed lust. There must be an element still missing from this interpretation and that is to whom the verse is directed. It is directed to men who know what it is like to lie with a woman IE married men. Had the verse been just a condemnation of homosexuality it would have read, "Do not have carnal relations with a man."
In order to clarify the literal intention of the verse the definition of to'evah is once again under scrutiny. If lying next to a man potentially leads to depravity and depravity is defined as perversion and to pervert something means, "To lead astray" then who is being led astray by lying beside a man? Clearly any man who regularly lies with a woman is prohibited from lying beside a man because it may lead him astray from his commitment to her.
This interpretation is supported by the second century Torah commentator Bar Kapparah, who wrote, "to'eh ata bayou go astray because of it" (Babylonian Talmud, Nedarim 51B). Rebecca Alpert writes, "Tosafot and R. Asher ben Jehiel assume that to go astray means to abandon your wife and disrupt family life."
Preserving the family is so vital to the Israelites that the prohibition against adultery is one of the Ten Commandments. Deconstructed in this manner it becomes evident that Leviticus 18:22 is not intended as a prohibition against homosexuality rather it is a prohibition for a married man to lust after another man and abandon his family.
