Why would scientists be making personal decisions for individuals?
And what pre tell is sexual morality (aside from adultery and rape)?
Widower Judah looking for a prostitute?
Rahab being a prostitute?
Lots daughters both boinking their father?
A duty to Boink your dead brother's wife to provide him an heir?
It seems to me as long as two consenting adults weren't married or engaged, to sex or not to sex was up to them. (Exception for dead brothers with no heir) No repercussions either.
