Animation stages not starting at 1 by default

[KTF]

Hi,

I seem to have an issue where everytime my sims autonomously pick an animation, there is a random chance that they might begin with an animation stage that's not the first one.

 

For example :

When using the "make a move" option, my sims will find their location and immediatly start going at it, almost to the point of climax immediatly at the start. With animations authors such as azmodan, I can even see that they begin at the third or fourth stage of an animation playlist, which isn't what i would like to happen. 

Instead I would much rather that they start with foreplay or at least the first animation of the stage and the rest should unfold naturally.

 

What's the setting that prevents sims from using any other animation stage that's not the first one ?

Thanks
