"If its possible and she has a G-spot orgasm would we have to stop intercourse because of all the liquid and the intense orgasm she has?"
Conditions for her to stop calling stop are:
1. She feels peeing due to overstimulation of the urethral nerve.
2. She has fully discharged her sexual energy.
3. She has gotten numbed in her face, hands, legs or whole body, resulting in waking up the sympathetic nervous division that automatically fires up the "Flight" command to defense her body function or organs (particularily, the heart and lung). Level-7 Orgasm will trigger the "Flight" command.

"When a man has an ejaculation is that an orgasm?"
Not necessary. If it is an orgasm, he must feel there is a sequence of the electric pulses running from his tail bone into his spinal cord, as a result of the prostate contraction.
