heterosexual women.
Well that explains a lot......
(5/08/06 - WASHINGTON) - Lesbians' brains react differently to sex hormones than those of heterosexual women.
An earlier study of gay men also showed their brain response was different from straight men -- an even stronger difference than has now been found in lesbians.
Lesbians' brains reacted somewhat, though not completely, like those of heterosexual men, a team of Swedish researchers said in Tuesday's edition of Proceedings of the National Academy of Sciences.
A year ago, the same group reported findings for gay men that showed their brain response to hormones was similar to that of heterosexual women.
In both cases the findings add weight to the idea that homosexuality has a physical basis and is not learned behavior.
"It shows sexual orientation may very well have a different basis between men and women ... this is not just a mirror image situation," said Sandra Witelson, an expert on brain anatomy and sexual orientation at the Michael G. DeGroote School of Medicine at McMaster University in Hamilton, Ontario.
"The important thing is to be open to the likely situation that there are biological factors that contribute to sexual orientation," added Witelson, who was not part of the research team.
The research team led by Ivanka Savic at the Stockholm Brain Institute had volunteers sniff chemicals derived from male and female sex hormones. These chemicals are thought to be pheromones -- molecules known to trigger responses such as defense and sex in many animals.
Whether humans respond to pheromones has been debated, although in 2000 American researchers reported finding a gene that they believe directs a human pheromone receptor in the nose.
The same team reported last year on a comparison of the response of male homosexuals to heterosexual men and women. They found that the brains of gay men reacted more like those of women than of straight men.
The new study shows a similar, but weaker, relationship between the response of lesbians and straight men.
Heterosexual women found the male and female pheromones about equally pleasant, while straight men and lesbians liked the female pheromone more than the male one. Men and lesbians also found the male hormone more irritating than the female one, while straight women were more likely to be irritated by the female hormone than the male one.
All three groups rated the male hormone more familiar than the female one. Straight women found both hormones about equal in intensity, while lesbians and straight men found the male hormone more intense than the female one.
The brains of all three groups were scanned when sniffing male and female hormones and a set of four ordinary odors. Ordinary odors were processed in the brain circuits associated with smell in all the volunteers.
In heterosexual males the male hormone was processed in the scent area but the female hormone was processed in the hypothalamus, which is related to sexual stimulation. In straight women the sexual area of the brain responded to the male hormone while the female hormone was perceived by the scent area.
In lesbians, both male and female hormones were processed the same, in the basic odor processing circuits, Savic and her team reported.
Each of the three groups of subjects included 12 healthy, unmedicated, right-handed and HIV-negative individuals.
The research was funded by the Swedish Medical Research Council, Karolinska Institute and the Wallenberg Foundation

"Nobody chooses their sexuality, gay or straight, it's genetically ingrained. The sooner people understand this, the better."
I would disagree with that statement only in that it creates an absolute. As I see it, I would think there are some people who it is genetically ingrained, and others who make the choice themselves based on personal experiences. Example: some people may have been traumatized by someone of the opposite sex, and that could very easily lead to their attraction to the same sex. There are too many factors involved and too many people out there with which have all had different life experiences to conclude that "nobody chooses their sexuality" as an be all, end all arguement.

Humankind should rid themselves of the base act of sexual gratification, if we are ever to evolve. We are no better than the lowest animal putting personal gratification in the forefront..for what? a pleasant feeling, convulsive spasm.. What are the long term benefits? Nothing at all.
If we would stop putting such a priority on sex, sexual preferences, etc. and climb the ladder rung from the mentally stunted sexual personal pleasure addicts/monkeys, we just might find that we could put our brains to better use.
As it is I see humankind as drooling idiots looking for their next rub.

Bebo, call it what you want but the bottom line is that what it is, is undisputable and that is that it is procreation.

oh gimme a break! What about those that are so called bi-sexual....did THEIR genes like split in half or something??
Much of homosexuality is pure pervertedness. Some boys want to be girls and some girls want to be men. like spock-o-rama feni-dix.
Pi, procreation? what the hell have u ever procreated? You talk a big bullsh* but you cant stay away from strip clubs...you and your god*damn demon seed.

WOW...all that from the supposed 'sex pot' herself? ROFLOL...... How funny.
Maybe rather than sex...we should all become compulsive SHOPPERS/SPENDERS like maggie....since she enjoys that so much more.
--
We wouldn't have 'evolved' if we didn't have sexual desires ....and act on them to procreate and enjoy ourselves. That's what guarantee's our survival as a species.
------
I've always felt very sorry for women who don't enjoy sex and who see it as an obligation of some sort. How extremely sad for them. Maybe they've never been with a REAL man....one who pleases them too.
Oh well...their loss...that's for sure.

LOL.. this from the fat woman who hasn't even been able to FIND her sex parts until a couple of weeks ago when she toppled over on her head!
ROFLMAO!
Having sex for procreation is one thing, horny old decrepit slobs having sex for stimulation is another.
I've always found it sad to hear obese old WIDOWS displaying their horniness on chat boards, the closest thing you've got to a real man in many years is the plunger that you painted president bush's face on....LOL

No, unlike you I don't need or want the rub.
I have had all the sex I wanted in this lifetime. My pleasures cost a little more than just a rub but are so much better.
But hang in there old man you have a good wife who I assume agrees with you, so what have you got to pout about..

'soo ahh what do ya do with that dried up old cooch, just pee out of it?'
'maggie, dont go away...inquiring minds want to know.'
Ahh, with the way that you worded your inquiry, I would think that most inquiring minds would not want to know.
Oh and yeah sure Classic, your niave but since you have got one of those inquiring type minds here's a little Spanish proverb that may help to explain your misunderstanding about what I said. Quien busca halla, perro que no anda hueso no halla. In other words try Googling it but don't be too lazy about it.
