Just those in a committed relationship? That's discriminatory over the ones who are still single! ;)
Well in that particular case, the Bible is wrong, just like it is in a hundred other matters like the black pudding. Especially since more and more studies tend to show it's genetic, or rather epigenetic, so a completely natural phenomenom. Better swallow it and focus on matters of faith rather than matters of fesse (French for buttocks, pronounced the same way).
