I would say it is better not or Makrooh for the possibility of such chats could be viewed by others in one way or another. In many times we take technology granted for privacy but the reality it is not. So if it was just texting or talking it should be no problem.

 

But I will be totally against having people show their private parts in intimate positions on such chats.

 

Almighty Allah knows best.
