Boy Sex With Matures
Recent studies reveal that after birth girls are already better at reading faces and hearing human vocal tones. Incredibly, during the first two years of life a baby girl's ovaries will pump adult levels of estrogen. From six to nine months, a boy's testicles are flooded with adult levels of testosterone.

\"The studies that were done with children around 12 months old where their moms went in a room with them and they were told not to touch an object,\" recounts Dr. Brizendine. \"The boys would just go right for the object and touch it. The girls would hear their mom's voice, turn around, look at their mom's face, and stop. Boys don't hear the complete tones in the female voice.\"
For years, brain studies focused primarily on male subjects. But in the '90s, the government began requiring that all its studies include women. At the same time, powerful new brain imaging technology and sophisticated animal studies provided scientists with tools to map human emotions and gender differences.
\"When I hang out with my guy friends, it's really odd to think that every, like, whatever seconds, they're thinking about sex,\" said high school student Sara Johnson. \"And that you can't stop them from thinking about that.\"
\"Actually, there is a hormone that gets released when girls are, sort of more intimate with each other -- in terms of talking and fixing each other's hair and doing stuff. That's called oxytocin. It's a hormone that's released in the brain that's kind of a \"feel good\" hormone.\"
Her classmate Chris Chun offered an explanation: \"Guys aren't supposed to feel 'Oh, I feel sad cause my girl broke up with me.' And I think that's what sucks, is that we're expected to keep our feelings inside, and not have any.\"
Studies have shown that, within about 48 hours or so, a mom can pick out the cry of her own baby above other babies. It could be that human evolution has been hard-wired in some ways to protect infants and propagate the species.
\"It's a struggle I live with everyday. Being at work, sometimes I feel guilty about being there. Sometimes being at home, I feel like I should be at work,\" said Cheyette. \"And it's not just me, it's every mom that I know.\"
The hormonal maturation of females is considerably more complicated than in males. The main steroid hormones, testosterone, estradiol, and progesterone as well as prolactin play important physiological functions in puberty. The production of gonadal steroids in girls starts with production of testosterone, which is typically quickly converted to estradiol inside the ovaries. However the rate of conversion from testosterone to estradiol (driven by FSH/LH balance) during early puberty is highly individual, resulting in very diverse development patterns of secondary sexual characteristics. Production of progesterone in the ovaries begins with the development of ovulatory cycles in girls (during the lutheal phase of the cycle), before puberty low levels of progesterone are produced in the adrenal glands of both boys and girls. Estradiol levels rise earlier and reach higher levels in women than in men. While estradiol promotes growth of the breasts and uterus, it is also the principal hormone driving the pubertal growth spurt and epiphyseal maturation and closure.
The onset of puberty is associated with high GnRH pulsing, which precedes the rise in sex hormones, LH and FSH. Exogenous GnRH pulses cause the onset of puberty. Brain tumors which increase GnRH output may also lead to premature puberty.
The cause of the GnRH rise is unknown. Leptin might be the cause of the GnRH rise. Leptin has receptors in the hypothalamus which synthesizes GnRH. Individuals who are deficient in leptin fail to initiate puberty. The levels of leptin increase with the onset of puberty, and then decline to adult levels when puberty is completed. The rise in GnRH might also be caused by genetics. A study discovered that a mutation in genes encoding both neurokinin B as well as the neurokinin B receptor can alter the timing of puberty. The researchers hypothesized that neurokinin B might play a role in regulating the secretion of kisspeptin, a compound responsible for triggering direct release of GnRH as well as indirect release of LH and FSH.
Furthermore, as physical and emotional differences set them apart from people in their same age group, early-maturing girls develop relationships with older people. For instance, some early-maturing girls have older boyfriends, "attracted to the girls' womanly physique and girlish innocence." While having an older boyfriend might improve popularity among peers, it also increases the risk of alcohol and drug use, increased sexual relations (often unprotected), eating disorders and bullying.
In the past, early onset of puberty in boys has been associated with positive outcomes, such as leadership in high school and success in adulthood. However, recent studies have revealed that the risks and problems of early maturation in males might outweigh the benefits.
Early-maturing boys develop "more aggressive, law-breaking, and alcohol abusing" behaviors, which result in anger towards parents and trouble in school and with the police. Early puberty also correlates with increased sexual activity and a higher instance of teenage pregnancy, both of which can lead to depression and other psychosocial issues. However, early puberty might also result in positive outcomes, such as popularity among peers, higher self-esteem and confidence, as a result of physical developments, such as taller height, developed muscles, muscular male breast and better athletic ability. 041b061a72
