A few thoughts
One of the annoying things about our society is the way it deals with sex. Frankly it is both repulsive and annoying how our society overtly sexualizes so much.
Since our society at least in the west is obsessed with sex in the sense of sexualizing so much, waning interest is frequently viewed has some sort of calamity, a disaster to be thwarted, retarded and reversed. Even societies that make much of a premium on female modesty and repress overt sexuality in fact obsess over sex.
