No problem at all. Nothing a man and woman could possibly do is morally equivalent to any sex act between two people of the same sex. God never placed any retrictions on sexual acts between man and wife, but he absolutely forbids any kind of homosexual act. If TX law forbade any sex act between man and wife, it was a bad law and should have been repealed. Personally, I believe heterosexual anal intercourse is depraved and demeaning, especially to the female, but it shouldn't be made illegal.
BTW, sodomy is a general term to describe homosexual acts of all kinds. The notion that it only means anal intercourse is simply wrong. The word is derived from Sodom, as in Sodom and Gommarah, and nowhere in the bible is the homosexual sin of the Sodomites specified as being any one particular act. Sodomy is just the practice of homosexual sex in any form.
