<human>: The boy is a high school junior and I'm a freshman. We've known each other for about three months. He is not pressuring me into anything- I've been making my own decisions. He's a great guy and unlike anyone I've ever met. We're both good kids and we're respectful of each other.
My parents have told me that I'm not allowed to date until I'm 16, and they think that because he's older, he must be trying to take advantage of me. I know people say that all high school guys only want sex, but we've talked about it and I trust him. The thing is, we like each other despite our age difference, not because of it. We're both willing to wait until I'm 16 if necessary.
I don't think my parents have a huge problem with trusting me, they just think I'm naive. I've gotten in trouble once for texting him too much, which possibly made them trust me less. We're not allowed to hang out outside of school, and I'm not willing to go behind their backs and do it anyway. 
I don't normally disobey my parents- I understand they want what's best for me. This is an exception, because I feel like he's worth it.
My twin sister recently started liking a sophomore. My parents have met him and they like him, so I've been trying to convince her to talk to my parents with me.
So what can I say to convince my parents to let me date?

Summarize the given text in a few sentences.
<bot>: Parents won't let me date a guy who is two years older, especially because I'm not allowed to date for another year.
