Is this supposed to be a question?
Hey there! If you shuddered while reading a story, there may have been something disgusting, spooky, or "cringeworthy" in the story.
Well, you most likely will have to take it 3 times, if you tense up, it will hurt alot, on the first time mostly. But afterwards, it wont. So Dont tense up, and dont get stressed. Its not very bad really. The first time is bad, but you wont feel it much.
