Heheheh. I LOVE this question.
There's been an incredible amount of confusion about this over here too.
Personally, I use my real name when introducing myself to either a Wing or a woman, to save both confusion and to be...well polite.

When it comes to the forums, I use "Cuboid". If anybody from the community calls me on my phone for the first time, 9 times out of 10, they say "Hi, is this Cuboid?" then I immediately know what the call is about.
However! For the sake of fun and flirtation, use whatever name or handle you like if you want to when it comes to approaches.
Something I've recently developed (Thankyou batchelorette Bunny Girls!) is to refer to myself as a pet name any of the girls might have had, or at least something they can all refer to me as if they're in a group. This will open them up more to your fun frame, and just appear more memorable, even if it's not who you really are.
