I would contest that you grew up at all.
St John Chrysostom on sex -- and he is known as the Pillar of the Church:
“How do they become one flesh? As if she were gold receiving purest gold, the woman receives the man’s seed with rich pleasure, and within her it is nourished, cherished, and refined. It is mingled with her own substance and she then returns it as a child!”
Why are you blushing? Leave that to the heretics and pagans, with their impure and immodest customs. For this reason I want marriage to be thoroughly purified, to bring it back again to its proper nobility. You should not be ashamed of these things. If you are ashamed, then you condemn God who made marriage.
St John Chrysostom
