Well, I feel like I should say something here. Although there have been encouraging replies given to this question, many of them have been dismissive and even quite uncaring.
From the perspective of someone who has also decided to wait until marriage, and since it is something I consider important, I can say I relate to this. I don't make it some huge deal, but it is a hope that I would one day meet someone who valued such a commitment as much as I do.
I also believe that God never intended for sex to be something shared outside of the commitment of marriage, maybe many people will think I'm too extreme and strict for saying that, but I think promiscuity and casual sexual relationships have done far more harm than good. (If they have even done any true, long-term good at all).
Anyway, it was frustrating to read some of the replies here, and to see this issue trivialized and made fun of. Sex is a gift from God, and our society today has made it into something cheap and ugly. (And all too common).
For me, it's about values and morals, and that is why it is something I have never done. I am not condeming anyone who has, but if you have made a personal decision to do so, that is no reason to trivialize someone else's commitment to wait.
