The sexual constitution is a set of body characteristics that determines the level of sexual need (a comfortable and demanded number of coitus over a certain period of time), the limit of sexual activity (the maximum number of completed sexual acts over a given period of time can be realized) and resistance to harmful influences affecting the sexual sphere. The sexual constitution is related to genetic factors, it is not influenced by either upbringing or the social environment. This is a constant that cannot be changed. The sexual constitution is of three types:

1. Strong — high sexual appetites, desire to have sexual intercourse once a day or more.
2. Average — moderate sexual appetites, desire to have sexual intercourse three to four times a week.
3. Weak — low sexual appetites, desire to have sexual intercourse from once a week and less often.

To identify the appropriate type, a scale of vector determination of the sexual constitution is used (G. S. Vasilchenko and I. L. Botneva). For men, the scale includes the following indicators:

1. The age of libido awakening.
2. The age of the first ejaculation, regardless of how it occurred — during sexual intercourse, masturbation or pollution.
3. The trochanter index. To calculate it, you need to measure the length of the leg from the large trochanter of the femur (it is easily felt if you shake your hips a little) to the floor and height. The trochanter index is equal to the ratio of height to leg length.
4. The pattern of pubic hair is horizontal (female type), with a transition to the abdomen in the form of a hair path to the navel (male type), with excessive hair loss (hypertrichosis, male type).
5. The maximum excess is the maximum number of ejaculations per day, over a lifetime, regardless of how they occurred.

Indicators	The sexual constitution
	Weak	Average	Strong
The age of libido awakening	15 years and older	from 12 to 14 years old	up to 11 years old
The age of the first ejaculation	16 years and older	from 13 to 15 years old	up to 12 years old
Trochanter index	less than 1.91	from 1.92 to 1.98	more than 1.99
Pubic hair loss	according to the female type	according to the male type	hypertrichosis
Maximum excess	3 и менее	from 4 to 6	7 or more

For women, the scale includes the following indicators:

1. The age of the first menstruation.
2. The regularity of menstruation.
3. The first orgasm, regardless of how it occurred — during intercourse, masturbation or in a dream.
4. The trochanter index.
5. The nature of pubic hair.

Indicators	The sexual constitution
	Weak	Average	Strong
The first menstruation	15 years and older	from 12 to 14 years old	до 11 лет
The regularity of menstruation	long-term violations for no apparent external reason	episodic disorders only in case of adverse effects	regular without pathology
The first orgasm	>35-30	20-25	<11-17
Trochanter index	less than 1.97	from 1.97 to 2.00	more than 2.00
Pubic hair loss	sparse straight hair	according to the female type	by the male type

What should I do if you and your partner have a different sexual constitution? First of all, it’s worth talking about it directly, expressing all your feelings and wishes. Sex is not only a coitus format, it can include oral sex, erotic massage, petting, as well as sex toy practices. It is important to resolve this issue in a compromise so that both partners do not experience discomfort.
