Well, first off I wouldn't compare yourself to reality TV. The show, which claims to celebrate celibacy, is of course going to show the most awkward, extreme versions of adult virgins because it makes good television. There is nothing wrong with being a virgin at 30, and certainly there's nothing wrong with being one at 25 either.
That said, while the newlyweds in the commercial for the show are virgins, that doesn't mean they have to be such freakish kissers. There's nothing wrong with wanting to keep your virginity until your wedding night, there's no reason why you can't kiss get physically comfortable with the person you're planning to spend the rest of your life with. Watch the kiss-- they look like two fish sucking food from each others' mouths. You can almost hear the TLC camera crew offscreen shouting "ratings goldmine!"
As for the virginity issue, the right time to lose your virginity is when you're ready. Not when your friends, movies or some reality show tells you when. You will know when the time is right, and you will (hopefully) be with someone who will be understanding and patient and feel as strongly for you as you do for then. You are right on the money -- it will happen when you're in love. Sometimes that takes a time to find. And you'll be better emotionally equipped to handle it than you were when you were 16 or 17 or 18 or 19 or 20 or whenever society thinks the "average" person loses their virginity. The truth is that everyone has their own pace. It's not a race, and the worst thing you can do is lose it before your ready.
Also remember -- people make a big deal about their first time, but losing your virginity is just the beginning. Great sex -- and real connection-- comes afterwards.
