I think yes. There is a subtle difference in the sexual behavior of homosexuals compared to heterosexuals: the sexual movements during sex. Thrusting movements during heterosexual sex are stereotypical, almost reflexive movements that appear upon sexual arousal. They are regulated by the sexually dimorphic nucleus in the medial preoptic area (SDN-POA). In heterosexual females there are vaginal muscle movements, which manifest with the urge to grasp and engulf. Homosexuals (both males and females) have issues with this reflex. I think that the reason is diet and stress, which affect the development or functioning of the SDN-POA.
I began to study the issue as part of my masters thesis on the effect of sleep on mental disorders, but later did a thorough study with the intent to publish. Given that the topic is taboo in the medical profession and that I am not a career researcher, I published it on my website and you can find it attached. modern-diet-and-stress-cause-homosexuality.pdf 919.28KB 52 downloads
