Sexual Behaviors

Here are two extracts taken from a book i'm reading that i feel to share because it confirms two ideas that i had already formed previously in my mind.
Sorry if the sentences aren't fully proper the text was translated from german to french then from french to english.

"Male and Female are noticeable here by different degrees of compatibility between the three main sources of impulse : aggression, evasion (escape), and sexuality;
In a male there is no mixing between the motivation of evasion and sexuality : if his partner instils fear inside him (if he is affraid), his sexuality is completely non-existent.
In a female the same relation exists between aggression and sexuality : the female "respecting" so little her partner that her aggressiveness isn't completely eradicated, is unable to react sexualy toward him. She attacks him furiously independently of her hormonal state."

"The loose relations and, in a way, unilateral existing, with geese, between the ceremony of triumph and copulation, shows analogies quite precise with some behaviors seen amongst humans regarding the fact of "falling in love" and the physical sexual intercourses.
The "purest" love leads, by the way of tenderness, to physical contact, without it being considered as the essential element of this link. Inversely, the stimulating situations and partners provoking the strongest sexual impulses, aren't necessarily the same that make us "fall in love passionately".
With geese those two cycles of functions can dissociate and become as independent one from another than with humans. This doesn't impede that "normally" it goes by pair and must concern the same partner to fill up its use in the interest of the species."

(So the feeling of love and the impulse of sex are definitely two separate things.)
