While this is an entertaining topic initially, it ends up being rather... flaccid. (like that?)
There is plenty of justification for both sides of the equation, so if you are an oversexed nymphomaniac (and yes, the term actually is gender-neutral, although most people immediately associate it with females) or a closet puritan (not that you'd admit it here), you are entirely correct in your opinion.
Why? The old "self-fulfilling prophecy" saw. Basically if you're not comfortable with having sex before marriage, and you do it anyway, you're going to feel a shit-ton of guilt and regret. If you're of a more sexual bent and you abstain until you're married, you're going to feel a whole lot of resentment and regret that you wasted so much time you could've been knocking boots.
So sit down, logically think about your values and beliefs (i.e.- leave your junk in the box, Justin: thinking with your hormones will doom you whether you're male or female), decide what suits your morals and goals, and then make a plan and follow it to accomplish those things. Find someone who you share those values with-- and be honest about it-- and you'll be far ahead of 90% of the couples prior to 1970.
The tragedy of the situation is, as ExodusInFlames mentioned albeit in a slightly different light, people make the decision based upon external influences, and end up unhappy. The truth? If you and your future wife are both abstinent, but you really are both emotionally and physically extremely attracted to one another, yeah on your wedding night it will only last 15 clumsy seconds, but that is going to be 15 seconds of the hottest, wettest, most fulfilling sex you will ever have, just because you both are so invested into it.
So don't give me the 'practice makes perfect' bullshit-- the first time is *always* going to be awkward, even if you've spent years wanking ov-- I mean reading the Kama Sutra. I still remember my first time, and yeah, it was awkward, but damn, if we weren't hot for one another. I won't brag, but I will say that my # of sexual partners > my age, and if there is one thing I've learned, it's that the only thing you should focus on is the attraction (and hopefully connection) with your prospective partner, because otherwise you're just a bit actor in an amateur porno.
