Ehhhh....I'm going to agree with most people on here, and say that it might not be the best idea. My ex was only 1 year younger than me, and the immaturity issue was huge!! We were always in different places in our lives-and that was just a 1 year difference!!
Plus-like, what are you going to do on Friday nights?? Go to the mall?? (I say that in all joking

) Seriously, you can do tons of things he can't-drink, go clubbing, vote-maybe even stay out past 11:00 pm. if you live in a place with an imposed curfew. And it would suck to always be doing these fun things wihtout the person whom you care about.
And for real-stagitory (sp??) rape is not even funny...people will prosecute...
