AGE OF LOVE?? Please Read>>>>>>?

I am a16 year old girl and I met a older guy at a farewell party this weeked. I am still in high school and he is out of high school. He is around 19-20 years old. He is respectful and is interested in similar things as me. We held a conversation for abour 1/2 and hour and he shyly asked for my number. He is a genuine guy, but there is a problem. My parents are concered with the age difference and the fact that they don't know him, as he just moved to the state. What should i tell him if he asks me out so i wont completely disinterest him? My parents wont let me date him until they meet him so what should i do in the mean time to keep from scaring him off?
