So glad this was brought up today. Based on the comments, I wanted to add a few things: It's not just emergency contraception that is less effective in women of greater body weight; other hormonal contraceptives have had similar issues, often showing mixed results in studies with some showing them to be less effective…

THIS.

Thanks for your very kind, generous words. If anyone would get that there are lots of reasons women have sex, and that orgasm isn't always one of the main goals, I should have known it would have been the lovely ladies of Jezebel.

Exactly. C&G are bacterial and can be treated/cured with antibiotics. Herpes is caused by a virus and can be treated - but not cured - with antiviral medications. The "both" refers only to C&G.

Be aware, too, that many MEN have HPV - and that HPV testing is not widely available for men outside of research settings.

I wish we knew the why! However, the systematic study of sex in the US is less than 100 years old. And frankly more pressing research (sexual behavior, risk behaviors related to HIV, sexual abuse, sexual dysfunction, sexual difficulties in connection with medical conditions) tend to be more fundable... and thus…

Would it surprise you that - in a relatively small (and young - less than 100 year old) field of sexual science - that there is no such study that answers the "why"?

Many men (and women, too) report having masturbated since before puberty. Though there's little research on early masturbation, what we do have doesn't suggest a negative impact later on. A number of men are less sensitive than other men and it's not easy to pinpoint the cause of their sensitivity, though many of…

The "four times likelier" isn't accurate (not what our research shows). It was far more likely to be a sampling artifact of our research.

Thanks for covering our research. The sexual orienation breakdown is likely a result of our sampling methods (i.e., the websites who agreed to post our study recruitment message). It's not an issue of "likelihood". Regarding men and exercise-induced orgasms and sexual pleasure, as noted in our article, they actually…

We don't know how prevalent it is due to our study methods (it was an online survey). My best guess is that it's not rare, as it didn't take us long to recruit women into the study, but I don't think it's a highly common experience either. Our research continues!

Anna North reported accurately - and her piece, which I'm aware of, is what I'd consider journalism. I don't expect a blog post to be a scientific paper. I do expect one that purports to be from a professor, and that quotes scientific research, to accurately reflect it.

You're welcome!

Hugo, as a professor I'm sure you understand the value of primary sources. The original research article is available online and while you cite the research article, it sounds like you didn't read it and, if you did, you got it wrong. I can send a reprint if you would like (feel free to email me).

This is actually NOT true at all.

Thank you for covering our research. However, please correct the article to say that most American women and men felt positively about vibrator use. Your article says the figures are about "half". However, it was about 3/4 of women and about 80% of men who agreed with the statements identified here (that vibrator use…

Far fewer were/are "asexual" but it is true that nearly all studies of male masturbation find some percentage that say they have not. As one of the researchers on this, and other, studies I've found this to be often the case and have no reason to believe that men or women lie about this very often.

Our survey was a nationally representative, anonymous survey completed on the Internet. It was conducted by researchers with years of experience interviewing adolescent women and men about their sexual lives. There is also other research that shows that teenaged women and men are quite honest about responding to…

For some men (especially young men ages 14 to 17, who were those we surveyed) there may be more stigma than many people realize. Even many of the college students in my classes experience masturbation and sex related stigma. Also, masturbation for young men does not always end in orgasm according to the men in my…

@thedopeshow: Even more wonderful then!! :)
