This describes a person with a fetish or kink as their only existing sexuality. People like this are unable to engage in standard (vanilla) sexual intercourse with anyone else of either gender and can only be aroused by the said fetish. Many people enjoy non-vanilla sexual practices from time to time such as bondage, rubber or ropes as a secondary sexual pleasure but a person with an ENTIRE non-vanilla sexuality can only respond to their secretly desired interest being the primary and sole sexual urge. Most of the time a non-vanilla sexuality is an incompatible one and a person with this are rarely married or ever in a long term relationship. It could explain the number of bachelors and spinsters, many known celebrities, who are acknowledged NOT to be homosexual yet are never seen with lasting partners. Non conventional and incompatible sexualities such as fetishes could be the largely unanswered dark area for lonely and seemingly incompatible people today and throughout history.
