How can I attract girls younger than me?

I'm a 22 year-old male who is highly interested in dating and sleeping with girls of the 16 to 18 age bracket. I like younger-looking girls, especially if they're voluptuous and haven't had time to ruin their bodies, and I'm also intensely nostalgic of my own youth. Forming relationships with younger girls has in the past allowed me to restore my spirits - it was my plain, simple, happy time. The problem is that I'm very intelligent, ambitious, mature, highly academically and professionally oriented - so, these girls can't really relate to me. They want someone uncomplicated and fun, like themselves. A girl can like interesting men, but that doesn't mean she'll have a clue or try to get a clue about the subjects that make them interesting. How can I make myself more relatable to 16-to-18-year-old girls?
