Well, in most cases in the Bible, it was written about men, with a few exceptions of women being used. But by omission, it's not necessarily the case that the writers either condoned lesbianism or not. We won't know, because there's nothing written about it.
But what these narrow-minded fools like Folau is forgetting, is that no matter the sin, whether it's murder, homosexuality, adultery, divorce, whatever, each and every sin can be forgiven, and it's not the place for false prophets to say which person will be judged by God and whether or not they will go to heaven or hell. Only God decides that.
