"Dragons" represent male sexuality

As a symbol throughout history, the dragon represents male sexuality and, specifically, the religious idea that male sexuality is something evil to be overcome. The dragon's "wings" are the man's testicles, the neck is the penis and the "fire" associated with dragons is semen. Because the dragon represents a negative view of a man's sexuality, the fire, the semen, is viewed as damaging, destructive and deadly, something to be avoided (ejaculation) as religious views in the past condemned the lustful nature of sexuality.
