To run this out a little further (for fun, or otherwise) most women demand a significant amount time to become stimulated during PIV sex to properly orgasm. Most men lack the required ejaculatory control to provide the woman with the time the need, regardless of their size. So, to manage this - a woman should be allowed to self stimulate themselves (with porn or without) using their own fingers, toys, or even request a partners skilled tongue or fingers etc., in order to be aroused enough to begin PIV sex, and subsequently orgasm during PIV.
