My question involves criminal law for the state of: Kansas.

Recently a friend was engaged in contact with a 15 year old girl via chat. He is 24.

He kept it clean with the exception of a described make out scene online but had nothing overtly sexual (no nudity, penetration, simulated sex, actual sex,etc).

He had a webcam with the girl, but again clean. She took off her shirt but was wearing a bra.

He realized this was wrong and cut off all contact with her. She was on his facebook but he blocked her.

He's kind of a slow guy, and I'm really worried something could happen to him. He gave her his name, and she saw what he looked like. Does this sound like the police? Should I be worried or am I overreacting?
