Apologies for Sun link 
"Sexual orientation will be featured for the first time in the census, which takes place every ten years."
This is good. Will be very useful to know about the LGB population, nice straightforward question. But hang on...
"National Records of Scotland revealed in a letter to MSPs they planned to expand the four basic categories initially proposed — straight or heterosexual, gay or lesbian, bisexual and other."
"The 21 “other” options for census respondents are mooted as androphilic, androsexual, asexual, bicurious, bisexual, demiromantic, demisexual, fluid, gay, gynephilic, gynesexual, homosexual, heterosexual, lesbian, pansexual, polysexual, queer, questioning, skoliosexual, straight and unsure."
Sigh.
