More on what I mean about spiritual pride being a danger to the virgin who has maintained virginity through great effort.
There are two extremes to the thinking that could lead to the concern that the OP is feeling. One is to feel a new horror concerning the sin and appreciating what a glamorous danger this kind of sin poses. The other is to feel a possessiveness about “being a virgin” that is in reality a kind of pride. I would guess that most of us have feelings that combine the two at least some of the time. (I mean that we both avoid sin because we love God and do not want to offend him and because we imagine would feel a loss in our self-image if we committed some acts, because we hold some repugnance for people “who would do such a thing” and don’t want to feel that same repugnance for ourselves.)
As C.S. Lewis put the devil’s goal in the Screwtape Letters, it goes something like this:
What you want is to keep a sly self-congratulation mixing with all his thoughts and never allow him to raise the question “What, precisely, am I congratulating myself about?”…
The absolute first and last thing that the devil will do to someone who is developing a habit of virtue or especially one who has accepted the grace needed to maintain a spiritual crown by personal sacrifice is to tempt the soul towards pride…that is, to tempt the soul to believe “I am not like other men.”
Contrast this with what Our Lady says of her perfect sinlessness: “My soul proclaims the greatness of the Lord; my spirit rejoices in God my savior. For he has looked upon his handmaid’s lowliness; behold, from now on will all ages call me blessed. The Mighty One has done great things for me, and holy is his name." That is our model for what attitude to take when we have reached some kind of spiritual or moral “attainment” or any praiseworthy deed or habit. That is the model for the attitude of someone who has maintained virginity in this world. It is an attitude pleasing to God, whereas the “I can’t believe all these people who fall. What kind of soul gives up such a precious gift so easily?” is in reality the attitude of pride. It goes beyond treasuring the virtue and into feeling pride over it. That sullies the gift, for it includes the presumptuous thought that it is the soul who heroically offers the purity to God instead of the soul more honestly and humbly being grateful that God has preserved the soul from mortal harm. As Our Lady goes on to say about those who are proud: “His mercy is from age to age to those who fear him. He has shown might with his arm, dispersed the arrogant of mind and heart. He has thrown down the rulers from their thrones but lifted up the lowly. The hungry he has filled with good things; the rich he has sent away empty.” If we are “rich” in self-congratulation about our “virtues”, that is our payment, and we will be sent away empty of reward from God, because of our arrogance, for the Lord said, “everyone who exalts himself will be humbled, and the one who humbles himself will be exalted.” That is what I mean.
