Sexual Constitution and Sexual Biography

Sexual constitution is one of the main factors that determines the severity of sexual desire. According to the definition of G. S. Vasilchenko (1977), “... the sexual constitution is a set of stable biological properties which are formed under the influence of hereditary factors and developmental conditions in the prenatal period and the period of early ontogenesis. Sexual constitution limits the range of individual needs at a certain level of sexual activity and characterizes individual resistance to pathogenic factors, which are characterized by selectivity to the sexual sphere”.

The concept of “sexual constitution” has gained considerable popularity in specialized literature. To determine the sexual constitution of men, G. S. Vasilchenko developed and tested for the first time a scale for its vector definition, which takes into account seven indicators, namely: I vector – age of sexual libido awakening, II vector – age of first ejaculation, III vector – trochanteric index, IV vector – pattern of hair growth pubic area, V vector – maximum excess, VI vector – time between marriage and entry into the zone of conditional physiological rhythm (CPR), which is equal to two to three sexual acts per week, VII vector – the age of the man at which he switched to CPR.

The first four vectors (I–IV) are closely related to the human genotype. They are used to determine the genotypic index of sexual constitution – Kg, which is the arithmetic mean of these vectors. V-VII vectors are used to determine the constitutionally modeled index of sexual activity (Ka). The arithmetic average of all seven vectors (I–VII) is called the phenotypic index of sexual constitution (Kf).

After determining the values of all sexual constitution vectors, the Ka/Kg index is also determined, which makes possible to find how much a man’s sexual activity corresponds to his constitutional capabilities. Thus, this indicator in the group of persons “conditional norm” was 1.18.

The article presents data on the female sexual constitution and the scale of its vector definition, which was developed and tested by I. L. Botneva (1983).

Recommendations for determining the sexual constitution of a person are offered. In addition, the article provides clinical observations of the author, which testify to the influence of sexual biography on sexual activity in order to take it into account when determining this constitution.
