Families support each other because that's just what happens. Where there is love, there is life. Life is super lonely otherwise.
Paul wasn't squeamish about sex so much as he was, I'm fairly confident, a self-hating pompous 1st century version of the Ivy League fancy Jewish Roman citizen misogynistic homo douchebag. He basically told young Christian men that premarital sex was a sin so only get married if you can't control your dick. If you can, leave the women be, they ain't shit. Nothing from Jesus ever said women were less than men or shouldn't teach, all that women should keep silent and ask their husbands when they get home bullshit was Paul. He also talked about wrestling with the weaknesses of the flesh. Dude was gay as fuck and super wanted to not be. Some sad shit.
