If you are a mistress and you do FTT on the guys, is it less than 10% of the guys who vomit during the beginning FTT, or more?

Of the guys who vomit, is it about half who want to quit or were they expecting to vomit and continue?

Do you let some quit or is it more or less mandatory that they "keep going?"

If you are a guy and vomited during an initial FTT session, how did the mistress or mistresses continue?
