The Different Kinds of Sperm

November 17, 2010 Lessons No Comments


So everyone knows what semen is for, right? Right, being the main subject of the final scene in a porno. Did you ever stop to think what’s really going on in our semen? Probably not, but I promised to write the article, so here’s the skinny on the spooge.

So everyone knows the story of the birds and the bees: your wingmen bees filter off the lady bee’s friends; you fill the lady bee with booze; and then you spend the next 10 minutes explaining to her that this never happened to you before (or is it just me?). Well, if you’re not me, you probably slept with her and sent forth your sperm soldiers.

Soldiers is a really appropriate nickname for sperm. Most people don’t know there are many different kinds of sperm that all work together to make sure you’re the father of that little kid no matter what you claim on the next Jerry Springer show. … Continue Reading

Premature Ejaculation — Something Evolution Selects For?

November 16, 2010 News, Research No Comments

does evolution select from premature ejaculation?

No matter what we do, it always seems to come back to semen.

We’re blaming this one on Jesse Bering over at Scientific American, who recently decided to examine the evolutionary merits of premature ejaculation.

Ejaculation, biologically speaking, has one function: to shoot semen into the female body, in the hopes that one of the sperm survives the hostile reception long enough to penetrate an egg. “Given these basic biological facts, and assuming that ejaculation is not so premature that it occurs prior to intromission and sperm cells find themselves awkwardly outside of a woman’s reproductive tract flopping about like fish out of water,” Bering reflects, “what, exactly, is so “premature” about premature ejaculation?” … Continue Reading

Teen Romance and Sex Ruled by Scarcity

November 15, 2010 News, Research No Comments

Remember highschool?

Remember high school? Yeah, Neither do we. But researchers recently released a reminder entitled “Terms of Endearment” — a paper studying the Darwinian mating habits of the high school student.

Based on data from the National Longitudinal Study of Adolescent Health (or, “Add Health”) — a huge compilation of data from surveys administered between 1994 and 1995 to students between seventh and twelfth grade, and periodically thereafter — researchers Arcidiacono, McElroy, and Beauchamp zeroed in on data relating to sex and relationships. Specifically, they wanted to know the likelihood and factors surrounding the partnering up of students.

They found that freshman girls and senior guys have the highest chances of partnering up, whereas the pickier senior girls and lowly freshman boys had the least. They also confirmed that teen boys are sex-crazed and teen girls place a higher emphasis on the relationship aspect of romance. … Continue Reading

Sex in Dire Straights in Country of Romance

November 15, 2010 News, Research 1 Comment

The Institute for Public Opinion, one of France’s most reputable market research firms, inadvertently busted a myth recently when it found that more than three-quarters of French couples lead impoverished sex lives.

Common excuses from both genders to skip sex? Headaches, exhaustion, and the children.

The BBC loved the report — most likely still sore from the Global Sexual Satisfaction Survey that showed the Brits aren’t doing too well in that department, either. … Continue Reading

Amazon Sells Pedophilia How-To?

November 14, 2010 News, teh inetrwebz No Comments

WARNING: Please note the content of this post may act as a trigger.

Amazon’s self-publishing feature for e-books allows anybody to put their work up for sale — a great feature for writers who haven’t had any luck with publishers or who see no merit in going that route in this increasingly digital world. The problem? The platform is open to anyone, including people like Phillip R. Greaves II, who has dragged Amazon into a heated argument over liability, with an e-book book titled The Pedophile’s Guide to Love and Pleasure: a Child-lover’s Code of Conduct. … Continue Reading

It’s Not So Complicated If You Map It Out

November 12, 2010 Culture, web No Comments

Labels. We may claim to hate them, but face it, most of the time, they really help simplify things. And when it comes to relationships, the simpler the better. Of course, few relationships are so cut and dry. Most have little features — or as Facebook, that terrible heteronormative tool of the patriarchy, calls them, “complications” — that make them so much more difficult to define.

Well, fear not. We have the solution. From the fertile mind of Franklin Veaux, creator of the Map of the Lands of Human Sexuality, comes a new visual way to behold the many shades of non-monogamous relationships:

Are We Too Focused on Orgasms to Enjoy Sex?

November 11, 2010 Opinion No Comments

Our editrix had a scathing piece on NakedCity LA a couple of days ago that questioned why so many news outlets were using a picture of Meg Ryan faking an orgasm as Sally in When Harry Met Sally on their articles discussing research being done on female pleasure and orgasm.

Not one to shy away from any topic, our favorite sex doc, Madeleine Castellanos took the opportunity to tackle fake orgasms on her own blog, aptly titled, Reclaim Your Sexuality. Her message resonates strongly with us, and we offer it here for your consideration: … Continue Reading

The Ingredients in Semen

November 11, 2010 Lessons No Comments


Last week, we examined why semen stings when it gets into the eye. Today we’re exploring the major components of semen:

Seminal Plasma (the liquidy part)

The main purpose of the seminal plasma is to provide a protective environment for the sperm during their long swim through the extremely hostile environment of a woman’s vagina. There’s gotta be a joke in there somewhere about harsh women, but it escapes me at the moment — possibly because I fear retribution from female readers. … Continue Reading

Orgasm Stock Image Fail

Can you tell the difference?

Doing a little research on a recent study about female orgasm by Barry Komisaruk, professor of radiology over at Rutgers, we encountered something mildly thought-provoking.

A few news outlets reporting on the female brain’s response to orgasm feature photos of Meg Ryan, in that infamous scene from When Harry Met Sally, in which she fakes an orgasm in the middle of Katz’s Deli. … Continue Reading

Gamers Won’t Be Seduced, Will Stare At Random Cleav Instead

That Steam allows the objectification and sexualization of female characters in a variety of its games but refuses to accept a game about actually engaging with women in a more interactive fashion is astonishingly backward.

FetLife Is Not Safe for Users

That the site doesn’t take measures to protect user content and has shown incompetence or negligence in regard to user privacy, all the while prohibiting victims from warning others about predatory behavior creates an environment where it is nearly impossible for members of the community to take care of themselves and one another. By enabling FetLife to continue espousing a code of silence, allowing the spinning self-created security issues as “attacks,” and not pointing out how disingenuous FetLife statements about safety are, we are allowing our community to become a breeding ground for exploitation.

Why You Should Vote No On Prop 35

Should people who benefit (parents, siblings, children, roommates!) from the earnings of “commercial sex acts” (any sexual conduct connected to the giving or receiving of something of value) be charged with human trafficking? Should someone who creates obscene material that is deemed “deviant” be charged as with human trafficking? Should someone who profits from obscene materials be charged with human trafficking? Should people transporting obscene materials be charged with human trafficking? Should a person who engages in sex with someone claiming to be above the age of consent or furnishing a fake ID to this effect be charged with human trafficking? What if I told you the sentences for that kind of conviction were eight, 14 or 20 years in prison, a fine not to exceed $500,000, and life as a registered sex offender?

Pretty and Calls Herself a Geek? Attention Whore!

If you are a woman, you might be given a chance to prove yourself in this community. Since there is no standard definition of what a “geek” is and it will vary from one judge to the next anyway, chances of failing are high (cake and grief counseling will be available after the conclusion of the test!). If you somehow manage to succeed, you’ll be tested again and again by anyone who encounters you until you manage to establish yourself like, say, Felicia Day. But even then, you’ll be questioned. As a woman, your whole existence within the geek community will be nothing but a series of tests — if you’re lucky. If you aren’t lucky, you’ll be harassed and threatened and those within the culture will tacitly agree that you deserve it.

Cuddle Chemical? Moral Molecule? Not So Fast

Zak’s original field, it turns out, is economics, a far cry from the hearts and teddy bears we imagine when we consider his nickname. But after performing experiments on generosity, Zak stumbled on the importance of trust in interactions, which led him, rather inevitably, to research about oxytocin. Oxytocin, you might remember, is a hormone that has been linked previously to bonding — between mothers and children primarily, but also between partners. What Zak has done is take the research a step further, arguing in his recent book, The Moral Molecule, that oxytocin plays a role in determining whether we are good or evil.

How to Avoid Pissing off a Stripper

Let’s talk about the strippers. Whether they like to be half-naked or not, whether they enjoy turning you on or not, there’s one thing they all have in common: they’re working. Whether you think that taking one’s clothes off for money is a great choice of career is really beside the point (is it a possibility for you to make $500 per hour at your job without a law degree? Just asking). These women are providing fantasy, yes, but that is their job. And as a patron of the establishment where they work, you need to treat them like you would anyone else who provides a service to you.
