I become "turned on" by the piece of female anatomy dubbed "MAMMARY GLANDS".
On face value, this is because their conspicuous exhibition elicits imagery of the infantile application of oral suction to the nipples of said tissue sacks; culminating in the process of LACTATION. The lactation produced, bears an indubitable resemblance to SEMEN; in concert, unmistakably creating the allusion (*in the dopamine intoxicated [male] cerebrum) of ORAL SEX ― specifically: EJACULATION / a "CUM SHOT" from the penis (*"money shot" {slang}).
In other words, the image of a baby sucking on a teat ("tit" {slang}) ― an action that ultimately produces a 'climactic' eruption of white[-ish], viscous fluid ― something the infant craves esuriently, engorges upon voraciously and is deeply satisfied by ― foments distinct and direct sexual responses within me.
Now, I believe this curious concupiscence stems from my infancy ― when, presumably, I too would have extracted nutritional sustenance from [my mother's] mammary glands. HOWEVER, I have an increasingly sneaking suspicion that the agitation of these erotic feelings, may in fact be―at their core―dare I say... HOMOSEXUAL IN NATURE
For the CULMINATION OF THE SEXUAL ACT is the ONLY reason that sex is partaken in; indeed, even exists in the first place ― i.e., the innate compulsion for spæcial procreation. Ergo, the incidental nature of suckling upon a mammary gland's nipple, surely cannot be the nub of any titillatory effects ostensibly inherent in this process...
Rather, I contend that it is most likely the VICARIOUS RELATIONSHIP BETWEEN INFANT-FEEDING AND "CUM SHOTS", that correlates with the otherwise [arguably] pædophilic phenomenon.
>Conclusion:
• TIT WORSHIP = COCK CRAVING
• ŒDIPAL COMPLEXITY = LATENT HOMOSEXUALITY
• AROUSAL FROM MAMMARY GLANDULAR VOYEURISM = FAGGOTRY
• FAILING THAT, YOU'RE A DIDDLER
