Let's just get simple on this. I will have to read the decision in it's full, but what I gather is, if a woman in Texas performs oral sex on a man, it is legal, but if a man does it to a man it is illegal. That is what the supreme court objected to, not morality laws.
If Texas said oral sex was against the law for everybody, the law would have been less troublesome to the Supremes.
And I understand from reports that the decision specifically addressed the sexual act is protected in the privacy of their own home.
