But a twin study showed that when one twin claimed whether or not to have a g-spot, the other twin did not make the same claim at the frequency one would expect if the g-spot was the expression of a genetic trait with straight forward Mendelian inheritance.

Therefore, the scientists conclude, the g-spot does not exist. At all.

How can this be? How can 56 percent of the women in a study claim that they have one, but there simply isn’t one?

There are several possibilities, including:

1) There is no g-spot and these 900 or so women only think they have one. But they don’t.

2) The g-spot is not a simple Mendelian genetic trait, but rather, exists because of some combination of genetics and environment. This is a family blog so we won’t discuss what is meant here by “environment.”

3) The g-spot is a thing … trying to be not specific here about what it is … that is real, but does not exist in any way because of genetics.

What do you think?

My source is this press report, hat tip to Virgil Samms, who noted that perhaps it is just that twins don’t have g-spots.

In short, the study found:

Emotional intelligence was not associated with … age and years of education, nor did we find a significant association between emotional intelligence and potential risk factors for [female orgasmic disorder] FOD such as age, body mass index, physical or sexual abuse, or menopause. We found emotional intelligence to be positively correlated with both frequency of orgasm during intercourse … and masturbation …. Women in the lowest quartile of emotional intelligence had an approximate twofold increased risk of infrequent orgasm … Low emotional intelligence seems to be a significant risk factor for low orgasmic frequency. Consideration of this behavioral risk factor may need to be incorporated into research into FOD and possible treatment approaches.

This is interesting, and probably a valid finding in that it appears to be statistically demonstrable that there is a correlation between measured emotional intelligence and orgasm frequency. The correlation is positive, modest (between 0.13 and 0.23 Spearman’s, and confirmed with logistical regression), and statistically significant.

What I find even more interesting than this finding (which is important if somewhat unsurprising) is that one can even do a study using matched pairs of twins and have a statistically significant difference in both emotional intelligence measured by standard tests and patterns of orgasm frequency.

Emotional intelligence is a brain thing and we might expect to see it vary for a number of reasons. Here we have evidence that genetics is not the only factor in this variable. I expect that among genetically typical individuals without pathologies, there would be almost no genetic effect, but the presumption of genetics is so strong that I fear most people don’t get that. Patterns of sexual behavior and physiology, which relates to orgasm frequency and distribution, may be very closely related to reproduction (though for reasons you may not expect). Again, we have measurable and (possibly) meaningful variation that is not genetic.
