No offense to those who want to wait, but every single person I've ever known who wants to wait till marriage has been a VERY closed minded individual and usually carries emotional baggage of some kind usually linked to trust.
Most are the hardcore religious type while the others are simply, for lack of a better description, prudes. Of course, I'm not saying everyone in the world who waits is like this, just the ones I've known.
IMO, relationships with them aren't worth it. Not because of the lack of sex, but... just because the surrounding issues.
It's beyond me why there's this illusion that sex is more special than it really is. It's a natural part of life. If you can take a crap every morning, then, if properly protected, you can have sex without any consequences whatsoever. Trust me, "god" won't hate you. You have the parts, so use them! Enjoy your life.
There are some I've known that will do everything BUT sex, and that baffles me. If you're gonna go down on another person, you might as well go all the way. There's really no sense in waiting as they're no longer "pure".
This also falls into the same category as those couples who refuse to live with each other prior to getting married. That's like randomly picking a car based on name alone and expecting to be happy with it.
Luckily for me, I never plan on getting married, so I'll never have to deal with this
