Mage etiquette? I'm gong for one Wednesday, should i be completely naked? what if i get a bonk on?

Wear your undies. Clean and decent pair if you please!!! I wear my panties when I get maged. You might get some wood when they work on your lower back. Just from the pressure. Don't worry about it, they have seen it before. Just don't be inappropriate about it. Pretend it is not there and it will soon go away.
