Girls have a super power they can use to live rent free in any guy's head pretty much eternally. All they need to do is catch them off guard with a compliment.
A guy will keep a shirt until it literally disintegrates if one time a girl said "that color looks good on you." Pretty much every guy that wears a particular cologne, wears that cologne because at some point a girl said he smelled nice. It's not even a horny brain thing I don't think. It's just that guys get so few compliments on their appearance that every single one is massively precious to them.
They should just block UK traffic like the porn sites do. This is an excellent way to lose a resource the government regularly uses.
