The rest of the film sinks deeper into the darkness by staring into the sun, Minter focusing on his parade of perversions with such intensity that they soon blur into allegory. The pallid squalor of Mariano’s apartment is exchanged for a rocky cave, which glows as red as a furnace and obfuscates the set’s backgrounds with its steam. “When there’s no light, and your eye’s can’t see, your mind’s eye can see what lies beyond.” With dialogue like that, it’s hard not to think of Mariano as Minter’s stand-in, or to cast ourselves as the pliable teens at his disposal.
Primary sex characteristics are those directly related to the sex organs . In males, the first stages of puberty involve growth of the testes and scrotum, followed by growth of the penis.  At the time that the penis develops, the seminal vesicles , the prostate , and the bulbourethral gland also enlarge and develop. The first ejaculation of seminal fluid generally occurs about one year after the beginning of accelerated penis growth, although this is often determined culturally rather than biologically, since for many boys first ejaculation occurs as a result of masturbation.  Boys are generally fertile before they have an adult appearance.
