A week or so ago, the Independent on Sunday (a UK newspaper) contained an interesting article about some research that has been published on what determines sexuality. As well as being interesting reading in itself, it did include a penis size element that I thought members of the forum would be interested in seeing and may well have comments/opinions on. I've transcribed a couple of the paragraphs below:
"Born Gay summarises the latest research into the pyschobiology of sex orientation, concluding that studies with twins show that around 30 to 50 per cent of sexual orientation is due to genes. The rest is the result of processes in the womb.
The genes involved in the sexual orientation produce receptors in the brain which absorb male hormones released by the developing baby's testicles. It is thought that in gay men these receptors are less sensitive or are blocked. The absence of testosterone results in the brain developing female characteristics, including attraction to men.
It is also believed that the unabsorbed testosterone affects the body's extremities. This would explain, Dr Rahman [the report co-author] said, why the finger lengths of adult gay men tended to be more male-like than those of heterosexual men, in that their index fingers are significantly shorter than their ring finger. (Women's index and ring fingers tend to be of equal length.)
The hormone may also be responsible for increasing the size of the penis, another extremity. A number of studies have shown that gay men are better endowed than heterosexual men."
Can't say I have strong opinions about that last supposition, though to be honest I haven't exactly slept around loads, and of the half dozen or so people I have slept with, they have seemed to have been all what I would describe as average (about 6") with just one being significantly bigger (over 7.5" I estimate and very thick). As for me, I think the difference in finger length seems to be true, but perhaps less so on the penis size front! (Although people have been complimentary about the girth)
