So, just how common is it for a guy to come inside a woman during sex, exactly? It's hard to get a good handle on the exact percentage because, really, no one is asking the right questions. A plethora of research includes both men and women as subjects, with studies focusing on everything from the sexual efficacy of sex toys to public restrooms. Still, reliable estimates are far from easy to come by.
A 2007 survey of more than 4,000 college students found that 59 percent of men had had involuntary ejaculations during sex. Male ejaculate averages about 1 to 2 cc (more than 40 to 80 milliliters), said Dr. Justin Katz, an associate professor of urology at the University of Medicine and Dentistry of New Jersey School of Osteopathic Medicine, but it can vary from a few milliliters to as much as 15. On a scale of 0 to 10, he added that men typically give a 7 or 8.
This is (relatively) new territory for women, said Dr. David J. Leras, associate clinical professor of obstetrics and gynecology at the University of California, San Francisco. For decades, women were aware of the fact that men ejaculate during sex, but felt they didn't have control over it. As more women are having sex, and more men are ejaculating, sex becomes more common, he told Mic. For heterosexual women, the onset of sex might be less enjoyable for many reasons — because they’re not in a relationship or because they’re premenstrual or because their partner doesn’t climax quickly enough — but related research suggests it might also be because they can't say no.
In the small world of gynecology, most doctors know these tensions well. During a walk-in at Brooklyn Urogynecology on a recent weekday, Dr. Christine Smith, the doctor's current patient, was explaining that she had erectile dysfunction and was having basic sex with her husband. Still, apparently, there was no one in the waiting room for her to turn to. d2c66b5586
