When cumming inside a woman, hold still or continue to thrust?

When you are having PiV sex, and you cum inside, do you prefer to continue thrusting as you shoot? Or do you hold still?

I normally hold still, but recently I have been experimenting with continuing to thrust in and out.
I've also experimented with pulling out halfway so I cum low down in her vagina rather than deep inside.

I guess variety is the spice of life, but do you have any preferences?
