An acquaintance of mine has recently had a baby, and she's been "expressing her milk" (using a gadget to milk herself) a lot, apparently. She's go enough to make breast milk soap...

Muslim sympathizers are like those keeping raccoon as pets, weeds as house plant, hyena/pitbull as house dog. They have twisted logic like no matter how you try to bent them, they're still twisting/gay

However I realize though, if you're truly liberal you SHOULD support religious tolerance which gonna turn out to be..religious freedom ^^
Fear of unknown being is very much embedded in conservative mind. So, if you're truly gay and in your agenda, you suppose to support islam because islam is the same as vietnamese, sri lankan, nigeria, tao, buddhism or anything different than you.
 
Male ducks have corkscrew penises.

Male muscovy ducks, for example, have corkscrew-shaped penises that spring out from their body in less than half a second and are 20cm long when erect. Other species' length varies from 1.5 to 40cm.

Some ducks also have barbs on their penises to scrub away competing sperm.

They twist in the opposite direction to the male duck's penis. But, crucially, they have dead ends they can try to send the males down if they don't want to have their ducklings.

Male ducks are notorious for attempting “forced copulation” with females.
So females seem to have evolved vaginas that make it hard for a male duck to actually inseminate them, if they don't want it to, by forcing it towards the dead ends.

Of course, the male ducks haven't taken this lying down. The more forced copulation a duck engages in, the longer the males' penises tend to be, according to a 2010 study in Proceedings of the Royal Society B.

In fact, male ducks grow a new penis every year (yes, you read that right). Which means they can vary the length depending on that year's competition.

But the females seem to be winning. Most times male ducks force themselves on females, it doesn’t result in fertilisation.
Only 3% of duck inseminations come from forced copulation.

When a female does want to mate with a male, she will contract and relax internal muscles that scientists think help make sex easier.

Similarly, the glans of the human penis is shaped in such a way that it pulls its competitors' semen from the vagina, enabling its own spermatazoa to flourish.

In this way, we can recognize the heritage of 'forced copulation' as a regular feature of, at least, our biology. (o)

I didn't even know chickens had penis. I always thought hens developed eggs on their own, and that chicks were born after having done sitting on the eggs lol. It's also interesting that they can push the semen to a "dead end" in order to prevent the fertilization. I don't think women have this feauture, and it's strange because we are a more advanced species than ducks...

That is too technical for me to comprehend the recognizing of forced copulations :lol:

I could see this working with circumcised guys... but how does this work with uncircumcised guys?

For your consideration...

Under conditions that raise the possibility of females engaging in extra-pair
copulations (i.e., periods of separation from their partner, allegations of female
infidelity), Gallup et al. (2003) also found that males appear to modify the use of
their penis in ways that are consistent with the displacement hypothesis. Based on
anonymous surveys of over 600 college students, many sexually active males and
females reported deeper and more vigorous thrusting when in-pair sex occurred
under conditions related to an increased likelihood of female infidelity.

Mind you, I think the notion of "female infidelity" as the evolutionary driver behind the scoopy shape of the penis is laughable compared to the much more sensible, though vile, idea that our bodies are the product of generations of gang rape.
 
I was fascinated enough to read through the whole document. Then found myself wondering how on earth one decided on doing a research paper on the subject.

It's certainly something to ponder while plunging the toilet the next time it's clogged. ;)
 
Urgh. American toilets.
Why do they block so often?

We use too much toilet paper, and most toilets are now "low flow" for water conservation... but you have to flush 3-4 Times to get everything to go down so you're not really conserving anything.
