For men, getting laid for the first time is harder than hitting a hole-in-one (again I apologize for my punnyness). Dudes don't know the cues and technique to woo effectively at first. The faster one loses it, the more experience and confidence earned compared to one's peers, the easier courtship becomes, the easier it is to find ms right and get bizay.
Women keep it because its so easy to lose for them. If one is at least disturbingly average, all she needs to do is ask. So women value it, and it gains more interest than harvard's endowment did over the last century. Of course, women don't value it as much in men b/c men tend to suck the first time.
For both sexes of course, regardless of their stance, losing it is pretty fucking magical. There are also those crazy mofos who believe virginity is the key (or keyhole) to heaven....which sorta explains why losing it is so pretty fucking magical.
Oh and for you asswipes out there, virginity is *given*, equally by both men and women. It cannot be a "taking" if you give it and should not be actually taken from anybody, male or female. Semantics, people! They most certainly DO fucking matter!

Parker: I took Christina's virginty.
Alex: God damn you, I wanted Christina's virginity.
Parker: Haha, sucks to be you.
For men, it makes them feel ashamed that they have it because they think it represents immaturity or something along that line. For women, it makes them lie that they have it because they think it makes them less of a slut.
For the religious and/or conservative, having it makes them believe they're imbued with magical powers, which may remain ONLY if they lose their virginity in marriage.
College Whore: I still have my virginity!
College Professor: I still have my powers!
