I was reading that thread and I saw someone mention pinching and blood. Terrified, I pressed on to try anyway and could not find the place to puch them up. I heard about these and they seem to hint at not needing tucking. Is that the case?

What thread sweetie? not sure bout the pinching and bleeding part??

The tucking thread, with the Wiki post in it. One lady mentioned that sometimes it pinches and leaves drops of blood in her panties.

I have never had any chaffing or bleeding, one reason might be I can longer get an erection so movement is minimal during the day and I use plenty of powder
