Is it normal not to be interested in love if you are less than 20?

I'm so young and I already don't believe in love. I'm disappointed in it. Everybody says love is the best and the most important thing in the universe. All people around me always think and talk about their boy-friends and girl-friends but I'm absolutely not interested in all that. When somebody falls in love with me and starts calling me, wants to spend time together etc, I feel that it is all a complete absurd. Why should I lose my time talking about nonsense with someone who thinks only of how to have sex with me? With someone who doesn't care about my hobbies,my interests,my inner world... Even if he pretends to I see it's just nothing fr them. Almost all movies tell love stories but they don't ravish me. It's so boring! I have so much different interests, the world is full of wonders, there are so many things and places to explore, so many different people to meet... Why am I obliged to lose my youth on such a fiction as love? Sometimes when I hear a love story it seems really exciting and romantic to me but I cannot believe such relationships were preceded by these terribly boring pastime! However, my friends find love so highly amazing... It seems impossible that thousands of years long people are mistaking, that all best workers of art were inspired by such an uninteresting thing. I've dated various boys but after a week or so I was bored... It's always the same! Stupid talks, kisses, flat jokes... Maybe I'm too lazy for love?
