Sexual activity other than intercourse carries some risk of sexually transmitted disease, and doctors should make sure their patients understand that, according to the American College of Obstetricians and Gynecologists (ACOG).
Many people may engage in “noncoital” sexual activities such as oral sex, mutual masturbation and anal sex to prevent pregnancy and cut the risk of STDs. However, all of these sex acts come with some degree of STD risk, and it’s still important for people to protect themselves, according to an ACOG expert committee. … more All types of sexual activity carry some STD risk | Health | Reuters
Fucking for science. Where do the masturbators sign up?
…For the first time – after hours and behind locked doors in an examination room in the Heart Hospital in London – a scientist is attempting to capture three-dimensional moving picture (or 4D, time being the fourth dimension) ultrasound footage of human genitalia in the act of sexual congress.
Jing Deng, a senior lecturer in medical physics at University College London, has made his name developing a new technique for viewing anatomical structures in motion. His website includes fairly astonishing 4D ultrasound footage of, for instance, beating hearts. This kind of imaging gives surgeons a preview of the structure on which they’ll be operating, in motion and from any perspective. It allows them to see what the problem is before picking up the scalpel.
In his most recent paper, Deng filmed a 4D “erecting penis“. With genital imaging, the hope is that the technology may help diagnose and treat patients with vascular or structural abnormalities, such as Peyronie’s disease, in which scar tissue in the erectile chamber on one side of the penis causes painful, crooked erections. … In his penis paper, Deng mentions the possibility of one day soon capturing an ultrasound sequence of real-time two-party human coitus. He envisions the scan as a potentially useful diagnostic tool – for instance, in teasing apart the possible causes of dyspareunia (painful intercourse)….
… But whether they are working in a packed call centre wearing headsets or from home wearing lingerie, phone-sex operators (or PSOs) are as diverse as the callers. I can definitely see the appeal of wanting to make money from talking dirty, like the Americans pictured here in Phillip Toledano’s compelling portraits. But these women (and men, some very successful PSOs have been boys with high-pitched voices!) have to do so much more: they have to morph into a role that is part therapist, part sexual surrogate. They also have to improvise and create multiple personae in order to play the submissive secretary, the naughty nurse, the adult baby, the porn star or the barely legal teen girl. …
