Has anyone got any practical advice on self-locating the Ventrogluteal injection site, that I've heard so many good things about? - I've looked up what info I could find and even the instruction on how to locate the site on someone else seems unclear to me.

So if anyone out there can elaborate on finding the site or put things into Layman's terms I'd be most grateful!?

(Btw, I ask this Q as my Ass is starting to look like a colander, and I'd rather take Rough-Love off a Circus Bear than shoot my Quads again...)
