Sex Questions/TMI filter

Haven't posted this since last year, and I've more than doubled my friends-of list, so I thought I'd post it again:

I have a filtered group that I post my explicit sex questions and TMI about my RL-sex-life things to. If you would like to be included in that filter, let me know.

The purpose of the filter purpose is not to exclude anyone at all, just to not TMI anyone who doesn't ask for it. So if you want in, please leave a comment!

ETA: The past posts have been rare, but have been chock-full of valuable and respectful conversations about RL experiences. I would love for that to continue, so please be sure, when commenting, that you are very sensitive of tone of voice. Lurkers are also welcome, if you just want to learn more about RL things. Mostly kinky things. ;)

slang help

I wasted 3 hours looking on the internet and can't find a convincing answer:

What is New Zealand slang for 'balls'? Bollocks? Knackers? BALLS?

Anyone who has been there or listened to lots of interviews or had a best friend whose great uncle twice removed went there in WWII, ANYTHING, please help me.
