Romantic Love goes counter to Christian Love, God wants us to be Prudent and not let ourselves be swept away by Passion (not to be dismissive of Passion). God wants us to have Temperance and have self-restraint.
It is Virtuous to not be impulsive, not to be naïve. There are plenty of women who were naïve and gave away their virginity outside of marriage.
Plenty of men give in to their impulsive nature to commit adulteries and murder.
