Is that true? Are there really gays who are "revolted" by the idea of "straight sex"? I've read countless posts by gays here on CD and never encountered that idea before. It's hard for me to comprehend that a gay person could find the idea of their own biological parents having sex as "revolting".
Yep, I think straight sex is kind of "icky". Although not so strong a word as "repulsive".
I find the relational behavior between men and women really bizarre too. So many straight men constantly whinge and complain about women, make derogatory statements about women, and often abuse women, yet they still jump want to jump into bed with women at every opportunity. Same goes for straight women. .
I almost feel sorry for them.
But straight people are "wired" that way, just as I am "wired" to be emotionally and physically attracted only to women, not men. So I don't hold it against them. Nor would I ever try to limit their rights or discriminate against them.
Well Gee-Wiz there jbcmh81, if "sexuality is set before puberty and most likely is, at least in part, biological", what's the other part that it would "most likely" be?
Here's a couple of very recent studies published in peer-reviewed Journals within the last 3 or 4 years.
They may shed some light on the subject for you:
The fetal brain develops during the intrauterine period in the male direction through a direct action of testosterone on the developing nerve cells, or in the female direction through the absence of this hormone surge. In this way, our gender identity (the conviction of belonging to the male or female gender) and sexual orientation are programmed or organized into our brain structures when we are still in the womb.
However, since sexual differentiation of the genitals takes place in the first two months of pregnancy and sexual differentiation of the brain starts in the second half of pregnancy, these two processes can be influenced independently, which may result in extreme cases in trans-sexuality. This also means that in the event of ambiguous sex at birth, the degree of masculinization of the genitals may not reflect the degree of masculinization of the brain.
There is no indication that social environment after birth has an effect on gender identity or sexual orientation.
Current evidence indicates that sexual differentiation of the human brain occurs during fetal and neonatal development and programs our gender identity—our feeling of being male or female and our sexual orientation as hetero-, homo-, or bisexual. This sexual differentiation process is accompanied by many structural and functional brain differences among these groups.
Brain scans have provided the most compelling evidence yet that being gay or straight is a biologically fixed trait. The scans reveal that in gay people, key structures of the brain governing emotion, mood, anxiety and aggressiveness resemble those in straight people of the opposite sex. The differences are likely to have been forged in the womb or in early infancy, says Ivanka Savic, who conducted the study at the Karolinska Institute in Stockholm, Sweden.
"This is the most robust measure so far of cerebral differences between homosexual and heterosexual subjects," she says.
Previous studies have also shown differences in brain architecture and activity between gay and straight people, but most relied on people's responses to sexuality driven cues that could have been learned, such as rating the attractiveness of male or female faces.
Brain symmetry
To get round this, Savic and her colleague, Per Lindström, chose to measure brain parameters likely to have been fixed at birth. "That was the whole point of the study, to show parameters that differ, but which couldn't be altered by learning or cognitive processes," says Savic.
The present study shows sex-atypical cerebral asymmetry and functional connections in homosexual subjects. The results cannot be primarily ascribed to learned effects, and they suggest a linkage to neurobiological entities.
During the intrauterine period the human brain develops in the male direction via direct action of a boy's testosterone, and in the female direction through the absence of this hormone in a girl. During this time, gender identity (the feeling of being a man or a woman), sexual orientation, and other behaviors are programmed.
As sexual differentiation of the genitals takes places in the first 2 months of pregnancy, and sexual differentiation of the brain starts during the second half of pregnancy, these two processes may be influenced independently of each other, resulting in transsexuality. This also means that in the case of an ambiguous gender at birth, the degree of masculinization of the genitals may not reflect the same degree of masculinization of the brain.
Differences in brain structures and brain functions have been found that are related to sexual orientation and gender.
The other transcripts I've read are in print Journals, not available for free online.
