"Sexual anorexia - have you heard of it?" Glamour coyly asks us this month. In the world of Glamour we all want sex, all the time -- and if we don't, we should do it anyway as it makes men happy and validates our existence as women. It's not a world in which women might have a 'preoccupation with the avoidance of sex,' as this problem is described by sexual health expert Dr Patrick J Carnes. 'Like self-starvation with food or compulsive dieting or hoarding with money, deprivation with sex can make one feel powerful and defended against all hurts,' he explains.
