Definition of terms

I remember looking up homosexuality in the New Testament at one point. Depending on the translation, you might not even see explicit mention of it. The KJV uses the term, "effeminate", whereas more modern translations refer to the "sexually immoral" (or something similar). I would be interested to see an analysis of the original Greek in the NT passages to see the actual meaning/connotation of the words in question. Depending on the results of such an analysis, you could make a case for a NT biblical view that homosexual intercourse had been "made clean" (a la split-hoofed meat animals), so long as the homosexual couples lived within the same moral guidelines (eg. refraining from fornication, orgies, etc) as heterosexual couples.
