By Roxanne Khamsi. Women may have a reputation for demanding lengthy foreplay, but they become sexually aroused as quickly as men, according to a new study that used thermal imaging to measure increased blood flow to genital regions. While watching pornography, both sexes reach peak arousal within 10 minutes, on average, researchers report. Earlier attempts to record sexual arousal have involved invasive probes and electrodes, according to Tuuli Kukkonen, who helped conduct the study led by Irv Binik at McGill University Health Centre in Montreal, Canada. For women participating in previous studies, this sometimes meant the use of an uncomfortable probe similar to a tampon, inserted into the vagina.

Using data from 61 previous studies, experts at the Proceedings of the National Academy of Sciences analyzed the brain activity of 1, men and women while they were shown sexual images. In other words, when men and women are watching pornography, their brains receive the same signals that activate feelings of pleasure. The study challenges the myth that labels men as more sexually aroused by porn than women, according to Hamid Noori, co-author of the research from the Max Planck Institute for Biological Cybernetics in Germany.
Let's face it: Sex can be kinda gross. With all those body odors and fluids being traded back and forth, it's no small miracle that humans voluntarily choose to copulate at all. But as scientists from the Netherlands have recently pointed out, our willingness to engage in sexual acts despite the yuck factor may be on account of a built-in psychological mechanism that temporarily reduces our feelings of disgust during sex — at least in women.
