Leviticus 18:22 (NIV) says “‘Do not lie with a man as one lies with a woman; that is detestable.” Leviticus 20:13 says more or less the same thing. 1 Corinthians 6:9 often loses something in translation, but the term arsenokoitai, which nowadays is often translated with some reference to homosexuality, is literally a compound word made from the roots for “man” and “to lie down.”
It seems clear from these texts that Biblical literalists should have no objection to homosexual intercourse, provided that it is not done lying down.
