Asexuality: not a sexual disorder, but a total or partial lack of sexual attraction. A lot of asexual people feel attraction (romantic, platonic, aesthetic or sensual), but have no inner urge to experience the attraction sexually with someone. They feel and experience a desire to get to know others, to be close to others. Most are physically capable of orgasm and masturbate regularly, although they occasionally report being unable to deal with their normal physical response in a meaningful way, and are embarrassed by it.
Loss of libido, or sex drive: temporary loss of sex drive is perfectly normal. Temporary loss of sex drive is normal.

A large proportion of young people in Japan are asexual. Nlcafé writes:
Japanese people under 40 have lost interest in traditional relationships. There are millions of young people who are not dating at all, and the number of those who are not even interested in sex is growing. The media have already dubbed this phenomenon the "celibacy syndrome"," writes The Guardian. But this could have serious social consequences, as Japan already has the lowest birth rate in the world. Its population - currently 126 million - has been steadily declining over the past 10 years and could fall by a third by 2060.
No dates, no sex
The number of singles has reached record levels. According to a 2011 survey, 61% of unmarried men and 49% of single women aged 18-34 are not in a relationship, up by around 10% compared to 5 years ago. And a third of those under 30 have never dated. A survey by the Japan Institute for Family Planning shows that 45% of women aged 16-24 are not interested in sex and are indifferent to any kind of sexual relationship; men are no different, with more than a quarter feeling the same way.
In 2012, fewer children were born than ever before, marriage is no longer attractive for either sex, and Japanese women have become more independent and ambitious.
