Actually, there is no such thing as a right level of interest. Its different for different people, and nobody can change their obsession or indifference about sex just by wanting it to be different. It can change, as we will see, but not by working on sexuality itself. No amount of sensuality training seminars' will make sex exciting for a hyposexual person. And no amount of talk therapy will put sex into proper perspective' for those who are hypersexual.
Sexual arousal is an altered state of consciousness, but it's a normal, healthy altered state.
The degree of interest in sex is directly related to how much time a person spends in non-ordinary states of consciousness. The normal states of consciousness for these people are different from those of othersothers. They often have lower self-esteem. They tend to be irritable. They have a burning desire to express themselves that comes out through writing diaries and journals or in doing art, sometimes obsessively.
