It is automatic, however if you fool around too much they may get stuck with the dialog. You should actually be grateful that you can initiate the dialog yourself. In many games when such a thing happens you would be forced to start over.

As for the "sleeping with Shani" thing it's unlikely you didn't as you have to start the quest for it in order to do the autopsy. So you simply have to fail the quest for it not to happen. More over Shani and Geralt almost had slept together at one point in the books and while they were interrupted it would still explain the dialog even if it doesn't happen in the game.
