Is it normal to think Why is Sex so important to teen girls?

I'm in my teens and I've often wondered "why"?

True some people are wrongly pressured into it or forced and they don't get to blossom into the concept on their own.

Why can't people take time to find someone they love? Why can't people have it with some form of meaning behind it? I don't understand people who can randomly meet someone and then have sex with them. They barely know them or their medical history and then the next morning they leave like what they did was nonexistent.

Sex isn't everything. True, I'm a virgin, but at least I can see that there are other important things in the world. If I'm going to be with someone, then I want it to be as long as possible. I'm not here for a meaningless fling. If I'm going love you, than I'm going to try to give you my all and I'd expect you to do the same. Not just for "me". Not just for "us", but for the relationship as a whole.

What ever, happened to romantics? What ever, happened to loves that were so deep, they could've been etched in stone? I refuse to follow this modern take on "love", but I prefer to follow the old-fashioned kind that actually meant something.
