In The Sims 4, the woohoo interaction is supposed to be automatic, but it never happens. This mod solves that problem.

This mod tweaks Snowball/Waterballoon/Mud fights and make them a little bit more dynamic. Basically, this mod removes reactions when hit or miss wich makes them take turns faster (they will still react when critically hit).

With this mod NPC will do "First kiss" interaction autonomously. Active sims won't kiss autonomously, but can be kissed. Being flirty helps with autonomy, less distractions the better. Requiriments for first kiss are the same (more or less).

There is mod, "Change Into Towel Everywhere", which is updated by LittleMsSam, but it stopped working for me long ago. So i made my own version.
