I am curious what a woman feels when the cervix is bumped during penetration. From the male end, it can be difficult to tell because the dick is harder than the bumped cervix. Sometimes you can definitely feel it getting tighter in deep, and it feels like the vagina does not want to go further (and this is the time to not go further unless invited), but it is not always that clear. Does it feel like a battering-ram bumping an unmoving object? Does the cervix feel pushed back into the parts deeper in the body? Or does the penetration force the cervix to flex inward, uncomfortably?
