Come Together, Right Now

Ok, so there is no good snarky way to introduce this next finding. Yet it will make you a little uncomfortable the next time you (or your wife or girlfriend) has an orgasm during sex. Unless you are using protection, which you should be doing anyway. Now get off my lawn.



Its long been theorized that women have more frequent orgasms with better looking and more masculine men. Its also believed that they did so as the man ejaculated, or soon after. This made pregnancy by that man more likely, as the orgasm took the sperm from the acidic environment of the vagina into the more hospitable cervix and uterus. The hormone oxytocin also makes orgasm more likely in women and it is shown to be more common during ovulation. Oxytocin also produces a semen like substance in the uterus, which helps protect and nourish the sperm. The substance also guides the sperm to the dominant oviduct, making fertilization more likely. Also, peristaltic uterine contractions help move sperm through the reproductive tract and reduces the flowback out of the vagina after sex.


The subjects were made up of 117 straight college students from north eastern university. The average age was 20.76 years old. The students met with the researchers two times, one week apart. During the first session, students had pictures of their faces taken, with a neutral expression and without glasses or jewelry. They then rated themselves at private computers and their partners in terms of attractiveness, as well as their own attractiveness. They were also asked to judge their partners masculinity and femininity, as well as those traits for themselves. The next week, the rating and judging was repeated. Data was also taken on how often the women had orgasms:

1. when they had sex with their partner besides penis/vaginal.
2. when they had penis to vagina sex.
3. before their partner did during sex.
4. after their partner during sex.
5. at the same time as their partner.
6. how often they had orgasms during masturbation.

The averages of the two sessions were then calculated. They found that the women with the most attractive, masculine men had the most simultaneous orgasms. A man's masculinity, a way of detecting his genetic quality, proved to be a good indicator of predicting if and when the woman would orgasm during penis to vagina sex.
