>>13721892We are neural networks.
To guide us through leaving offspring and continuing our genetic material, evolution gave us built-in detection for audio/visual patterns, behavioural patterns and pheromones.
The 1965 study Stimuli eliciting sexual behavior by Schein, M.W., & E.B. Hale determined that male turkeys will exhibit mating behaviour to a severed head of a female turkey if it smells right.
Males are attracted to cum dumpster behaviour and cum dumpster audio/visuals. We have long since lost our sense of smell, but I imagine it could play a factor for anybody who would take the plunge and physically "mate" with a Tranny. From what I read here on 4chan multiple times, the straight guys who've done so have been traumatized.
