The main problem with electrtical tape is the adheshive. You don't want glue in your ear...
Bondage tape is much the same as PTFE, but a bit thicker. Some people prefer it.. But meh.
Most people get problems with PTFE when it isn't lubed enough. Did it go translucenty?
And with small sizes it can be hard to get all the wrinkles out. I wouldn't bother taping anything less than 4g (6g was a total pain for my stubby fingers)
