Solved
the Wooden Throne woohoo animation is broken
my Sims autonomously woohoo'd in the Wooden Throne from Nature's Calling event and I noticed the animation where my one sim goes inside as the woohoo animation plays while the other sim is stuck from the kissing animation.
you can check the animation in the video I uploaded.
nvm, the problem was actually from a mod. thanks from telling me, after I removed my mods folder the animation worked properly.
