When do you think you can start dating?

I'm 15 years old this year, and I had never talked about dating with my parents and I had never have a date before. I don't know when is the time that I'll be ready for dating. To date with someone, we must be mature and responsible enough. I believed that my parents will like to give me some advise about when can I start dating. But sometime the person that our parents like, we might not like them. I am scared that if I had a crush on a girl and my parents don't like her, I won't know what to do.

My parents had told me that, I should start dating when I am in collage. They said this is the age that I will be mature enough and responsible. I don't know do I need to wait that long, but since I haven't got anyone girl that I like, so I am going to wait. If my parents caught me writing this 'title' they will call me and go and talk to me about when should I start dating.
