[Can someone help me with this avatar animation or what ever it is ?]

Yes it mentions:

Thank you for purchasing my first adult item! This is a sculpted horse **bleep**.

/1 erect makes you hard
/1 soft makes you limp
/1 semi makes half of it disappear so you don't no-clip through someone's spine.
/1 **bleep** makes you spurt
/1 stop lets you finish
/1 show shows the **bleep**, which may lead to a glitch.
/1 hide hides it, which may also lead to a glitch.

Important: There's a glitch where the dick displays all versions of itself at once. To fix this, cycle through the states (erect, soft, semi) and it should be fixed.

 

But enywhere I was i put in locla chat   /1   and nothing happends, do you know a place where I can use this   /1
