on ft and crying

in what portion of the time does a new or first timer start crying during ft, if the gal is insisting and the guy thinks he wants to back out or does not like it? I saw a vid with some crying and figured I should ask about that, since the usual vids we might see don't show that, but they are also probably with more experienced and desiring toilets!

I've seen gagging and retching, but I've never seen tears shed.

Yapoo (Japan) has a some videos showing that, but that is usually after epic (10+) use.

I myself have "wanted" to get to that point, and it's definitely possible with what Bastienne has put together, but I would probably be writing a check my body/mind can't cash.
