How do I tell mom to take me there....?

I've been wondering what its like to go to a gynecologist...there are some questions and things that I would like to ask. But I know mom, and she would just ask me why i want to go, if I'm having sex. She always avoids the subject and ignores me. She thinks its just for when you get pregnant or your period doesn't come. I'm 15 and I can happily say that I'm not hesitating to experiment my sexual life. How can I tell her to take me? I'm not sure that a 'take me to a gynecologist' is going to convince her.
