Anal Sex please help

Regardless of the bodies natural safegaurds when it comes to pain. I've been trying to find a serious numbing agent to use for anal intercourse, but I'm not having much luck. Does anyone know of any????


I've actaul even tried to look up local anesthesias, but I can't really find any. I only came across emla which contains lidocaine idk if it will really work tho.
