I'm pretty hardcore religious, and I am definitely against it.
However, most religious people know that the 'cultural phenomenon' is so far engrained into society that it truly would mess up the world to retract it.
I wish that our world was not the way that it is, but I'm realistic enough to know that it won't change soon.
At the end of it though, everyone is entitled to their choice, regardless of who agrees or disagrees with them.
Personally, I've been propositioned before which I turned down. Primarily because of my faith, but also because, when I get married, I want to be able to say to my wife that I waited for her.
Because I think that losing my virginity before-hand would be paramount to robbery.
But, again, only my personal opinion.
