Theme. As they are born, love differs by sex. It originates differently, is perceived differently than intended, and the effects match neither cause nor intentions of the giver, except in childhood, that is.
Women have two kinds of love to give. Mother love is ignited by confirmation of conception and magnifies upon delivery of her first born. It is unconditional and lasts for life. (It’s also the unique motivator that matches the male’s unique motivator to conquer the next available female. Neither gender has anything else to compare in intensity, dedication, and longevity, but those two motivators are enough to perpetuate the species as God designed us. Oh, perhaps the randomness of Nature developed our species to not die off, but with only two main motivators? Two motivators that click so easily and uniquely last for life seems more design than evolution to me. )
A woman’s main form of female love flows easily from the self-love she inherits at birth and is willing to share. Usually she shares it freely, because doing so makes her feel good about herself. However, it is conditional and dependent on whomever a woman thinks deserves her affection and appreciation.* She dispenses it at her pleasure, sometimes just to feel good about herself.
Effect on men. Female love has a different effect on males depending on their age group — child, adolescent, or adult.
As a child, mother love embellishes a kid’s self-development according to her instinctive determination of need. The child’s reactions, however, differ by sex. Girls appreciate nurturing mother love, because it aids development of self-respect missing at birth; it tends to make girls defend themselves sexually and want to duplicate mother as they grow up.
Boys are another matter. Mother love expands a boy’s appreciation of himself, and tends to promote growth of self-love missing at birth; it aids his desire and development toward being more manly like his father. By sharing her conditional love after first grade, mothers wean boys off of mother love, which begins to be too nurturing and unacceptable to boys after about their sixth or seventh birthday.
As an adolescent, the nurturing nature of mother love makes it unacceptable to teens of both sexes. They assume the role of adult in miniature form and expect to succeed without nurturing assistance, unless they ask for it.
Teen girls possess the conviction that they should spread their love and likeable boys are the sweetest targets. Girls pursue boys persistently, because loving another provides the fresh realization that they are growing successfully toward womanhood. Women love men and so teen girls prepare with an early start to prove how great their love can be. It’s a premature offshoot of their instinctive adult motivation to be a good woman.
Boys do not love girls. They neither understand the females’ loving ways nor want to put up with it except as it leads to sex. Teen boys, after puberty and until they mature about age 21, are in the business of figuring out how to keep themselves satisfied with themselves as life develops around them.
Pursuit of sex with girls is a welcome sport. It’s a diversion, however, from maturing faster. Teens figure things out faster by generating success in their lives. If they find too much success bedding girls, they continue into adulthood with an adolescent mindset to keep bedding females. Physically mature, mentally adolescent.
Adolescents do not love girls, because men do not love women as women expect they do or should. IOW, male love is nowhere near identical to female love. The closest a man’s love comes to a woman’s is how he is devoted to her as admirable action figure. Teen boys are little men trying to figure out how to master a higher skill level that calls for mating up sometime with a woman. Each does so efficiently without giving up too much of himself. Meanwhile, women compete with potential mates to expand the ‘too much’ part, to make a man invest himself more deeply in order to capture and hold her heart.
The effect of female love on adult men is next.
*Female love includes many other warming and pleasant emotions, but for simplicity here, I let affection and appreciation stand for all the others.
