What to do about this..?

Ok. So here is the problem. I am 15 and I met a 21 y/o at my church. We started talking on myspace, and that escelated to some type of relationship. We got a little carried away one night and ended up exchanging nude pictures. Today I was told I was going to my youth mininster's house, and wasn't told why. When I got there the girl was there crying. My minister and his wife were questioning us. She said the pictures were mistakenly sent to the wrong person, or someone did it as a prank. I denied any relationship.She did the same. Matters were turned over to authorities, and that's it so far. Please give any advice possible.
