Most of my background with Protestant churches was from a nondenominational church. Since looking into Catholicism and becoming a Catholic myself, I’ve noticed that the Catholic view on sexuality speaks almost nothing about keeping your virginity, but emphasizes the virtues of self-control and chastity. Most of the mentioning about virginity is about those who take vows or Mother Mary.
In my Protestant time there was a huge emphasis on virginity, and not being affectionate (they taught that holding hands can lead to kissing which eventually leads to more and more until sex is involved). They also taught that if you were no longer a virgin, then God can restore your virginity (I think inwardly).
Is this difference common, and why?
