Toxoplasma leads to feel pleasure from sado-masochism

Sexology is from Latin: sexus and Greek: λογία - logia. The scientific study of human sexuality, including sexual interest, behavior and related functions; the nature, causes and effects of sex perversion in both the individual and in society.

Normal sex is only consensual coitus between conscious, adult, married couple for procreative purposes. Any other form of sexual activity is a perversion, practiced by degenerates and leads inevitably to acquire mental and physical harm.

Perversion is when the natural brain's faculty of rational and objective reason is overwhelmed by uncontrollable, degenerated natural instincts of procreation and perverted emotions, which is a symptom of delusional, unconscious brain.

Sexual perversion starts with compulsive sexual excitement that leads to compulsive - excessive masturbation, a symptom of psychological and physiological dysfunctions that lead to all other subsequential, unnatural, harmful perversions.

Principal sexual perversions:

Masturbism Fellationism Sodomism

Voyeurism Exibitionism Fetishism

Promiscuism Swingerism Cuckoldism

Urolagnism Sado-Masochism Pedophilism

Transvesticism Homosexualism Transexualism

Everything rational and factual is welcome.

Rationality and objectivity lead to realism.

Emotivity and subjectivity lead to delusion.

Any kind of emotional absurdity is rejected.
