These days, a man can walk out of his doctor's office with a prescription for Viagra based on little but a self-report, but it still takes a woman, on average, 9.28 years of suffering to be diagnosed with endometriosis, a condition caused by endometrial tissue growing outside the uterus. By that time, many find that not just sex but everyday existence has become a life-deforming challenge. That's a blunt biological reality if ever there was one.
Or, since sex is the subject here, what about how our society's scientific community has treated female dyspareunia — the severe physical pain some women experience during sex — vs. erectile dysfunction (which, while lamentable, is not painful)? PubMed has 393 clinical trials studying dyspareunia. Vaginismus? 10. Vulvodynia? 43.
Erectile dysfunction? 1,954.
