If
secrecy is an essential part of your life, consider revising your attitude towards life, rather than patching it up by revising your noding habits.
If you're afraid of people not taking your E2 nodes for what they are, I'm tempted to say, it's their loss if they do. If your noder niece has a problem with finding out about your sexual life, it's her problem, not yours.
I restrain myself in writing here, too: for example, I won't easily write something that I know will hurt someone if they read it. But if you restrain your utterances, restrain all of them - a special policy for E2 is hypocritical.
