For the sixth or seventh idiotic time, male vampires are supernatural beings made of dead (i.e. no longer living) tissue. It follows that they’re not only incapable of fertilizing female eggs and/or creating a child, but incapable of having orgasms during vampire-human sex because they’re dead, and that even if they could experience some kind of simulated, super-vampire orgasm it would be just be for theatrical show (i.e., to make the female partner feel wanted and/or appreciated).
Certain stories have certain rules, and you can’t just throw them out because you feel like it. If you’re going to bite into the vampire sandwich, Stephanie Meyer, bite into it and live in that realm and stop cheating by breaking through the membrane.
