I hope you don't mind me butting in here, but please don't use duck tape on your skin, especially the sensitive, soft skin.
When you take it off, and you must, it can quite easily tear away huge chunks. The sort of chunks that will need an urgent trip to the emergency room.
I once saw a girl put duck take on her face, over her mouth. She was trying to make a point. What it did to her cheek, when she tried to remove it, was very nasty.
Also, it doesn't tend to come off very easily even under running water.
I hope you know that I and I'm sure everyone else here, know the pain you feel. I read the posts about binding and understand how important this is to you.
But I do hope you won't resort to any adhesive tapes. Especially Duck tape.
If I'm out of order, I apologise. But this is so very important.
