A friend of mine is worried about a certain thing he did a couple of months ago. Assume he lied about his age when he was 17 (now 18), and did erotic roleplay (ERP) with another individual who also lied about their age, and claimed to be over 18. This friend of mine lives in an overseas country, for example, Turkey while the other person lives in the US.
My friend asked for their age multiple times, and asked for their birthday to confirm and actually got confirmation that they were an adult (no actual IDs were sent). There were no actual, real life pictures sent or received. Just drawings and chatting. Could my friend get into trouble for something he did when he was also a minor? Could he be arrested when he visits the US?
