@Senpai it really depends on how dilated it is but it does take some time to get used to it. Like I totally don't recommend to use the whole fist when you have s** for the first times, but to get used to more and more as the time passes. It does hurt a little but it's a pleasant pain.(at least for me🫣) and it also depends on lots of other aspects. Sorry if its too much detail but I wanted to help
