I'm not following your point here. If women are scared the guy will leave, then you'd think this would cause better behavior on their part, not worse, which is what we see all around us. Christian girls aren't willing to wait for sex?
Yes, maybe the wording was poor. I'm saying the guys aren't willing to wait for sex for 1 to 6 months or maybe even until marriage. Meanwhile pious Christian girls don't limit their "pool" to pious men exclusively.
Therefore, the women even end up with so called "f*ckboys", but won't make exceptions for him either.
Christian girls, at least in my experience, have often times kissed many men, but aren't willing to sleep with just any random guy who isn't looking for something really serious.
I can even remember years ago making out with Christian virgins within an hour of meeting them, but sex before marriage was completely off the table.
