Sometimes you need to do this several times, to get the nerves in your cock in the right state. Pull out, let your cock desensitise, then go back in.

Your cock will lose it's initial sensitivity and you can fuck much longer.

You may find you have more trouble coming - you may have to really pound her to trigger yourself to cum.

This can also somewhat change the intensity of your orgasm.
