How common is sexting among married couples?

Earlier this year, we looked at a study that suggested sexting can be healthy in a relationship, but that study primarily looked at non-married couples and the average age for the behavior was, as you may expect, young adult.

The stomach is the way to a woman's heart, too

You’ve heard that romance starts in the kitchen and not in the bedroom. Well, researchers at Drexel University finally have the science to support that saying – but not the way you might think. Researchers found that women’s brains respond more to romantic cues on a full stomach than an empty one. The study explored brain circuitry in hungry versus satiated states among women who were past-dieters and those who had never dieted.

Previous studies have shown that men find female faces more attractive when the women are ovulating, but the visual clues that allow this are unclear. Now, new research investigating whether it might be to do with subtle changes in skin colour has shown that women’s faces do increase in redness during ovulation, but the levels of change are just under the detectable range of the human eye.
