Enneagrams?

Hey, so I've noticed that there is a section of our profiles to fill in our Enneagram results. I've taken a couple free tests online and the results I get are just a type...what's with all the w, so, sx, etc? I can't seem to find any information on it and I'm interested, so if anyone who understands it could help me out that would be great!

There are three variants: SOcial, SElf, and SeXual.

Basically, they sorta' mean where your priorities and loyalties get devoted: to society, to yourself, or to a specific person or very small group with whom you have a strong bond (not necessarily because of physical intimacy, but the "standard" is your significant other).

I'm an SX variant, because I put care for my significant other as a higher priority than both myself and society in general.
