... dont know how to trigger these

[Just Don't]

If you're talking about Sexlab animations, you need another mod to use them in game. Which one is up to you, there are several. Some examples:

• Matchmaker - spells to trigger animations (PC-NPC / PC solo / NPC solo / NPC-NPC).
• Follow me for sex - dialogue branches to select animations with the NPC you pick, MCM to configure a lot of stuff.
• SL Eager NPCs - a bit of everything, MCM to configure stuff.

 

A lot more, but listing them here would be pointless. Check the download section for other mods and delight yourself in what's available.
