Not quite through. Obviously what you said is correct. When a sex organ performs, it is performing sex, right?! Is this something new? Surely our knowledge should at least know itself. The organ doesn't produce masturbation. Intercourse is the designed purpose of having the organ to begin with. Procreation allows the specie to continue and is the purpose of the organs. Does the organ know procreation? It just knows to produce something called sex, in males the emission of sperm. Enough.
When I said that calling a developing baby in the womb of a mother a fetus isn't a good thing, I said this in reference to abortion (killing of the unborn child). The killer would rather think of the object killed as a fetus, right?
When a man uses his sexual organs to produce sperm whether it goes into a woman or not, the organ produces sperm and as far as the body knows, it is having sex, plain and simple.
In both cases, it is the mind that challenges simple facts and differentiates by its normal functions of complexity, yet the simple facts remain. As far as a loving mother is concern or for that matter her body is concerned, ITS A BABY!
