Personally, the thought of going in through the out door is a major turn off.
Don't forget, anti-sodomy laws didn't just apply to anal sex, but oral sex as well. In 4 of the 13 states that had/have such laws, they only aply to same sex couples (Texas, the state in question in this case, being one). The other 9 prohibited anla/oral sex for all couples. Lots of guys will be glad to know their wives/girlfriends can polish their knobs without breaking th law now.
IMHO, the court should have struck down the law on the basis of equal protection under the law premieses only. If Texaas wanted to ban it for all couples fine, that's teh state's right, but they can't single out just same sex couples.
