OK so this is a really basic situation, but many girls go through this even some guys. But when a couple is dating and the girl has morals to keep her virginity until marriage, but the guy thinks that it's okay and wants to do it. So the girl has to pick between breaking her morals for a guy or keeping them, because that moral is important to stay pure.
