A transsexual's (eunuch's) purpose is to validate the child, the offspring, and is thus used as a sacrificial offering to the gods, to appease the overall well-being of the population through its death, and to bring renewed sexual virility to the larger penis. It is perfect human sacrifice, because a larger penis has a higher chance of conception as it draws closer to the cervix. A transsexual with a small penis is in service to the greater male, and its sacrificial death is the definition of love and sacrifice.
The greater male and female come out unscathed, and they create new life from it.
