That should cover all bases (well, all letters at least!)

Then again, S could conceivably stand for 'Straight' (another potentially dodgy term, since if something's not straight, it's bent or crooked - so yet another term that could cast anyone other than a cis-gendered XX or XY hetereosexual in a negative light).

That's the problem with labels - you either end up in an alphabet soup while trying to cover every eventuality, or you adopt a handful (no more) of broad categories that can be easily understood by the populace at large, but leave a significant minority either without a category or straddling multiples. That is particularly the case with the socially acceptable 'norm' of the binary model - i.e. XX female prefers males, XY male prefers females, everyone else (who the media [conservative/traditionalist leaning sources in particular] often portray as 'not quite right in the head')

If only more people had an understanding of the complexity of biology. With chemistry, A + B = C, full stop. With biology, A + B could equal C, D, E or F depending on the quantities mixed, temperature, pH, humidity, atmospheric pressure, 'contamination' from outside sources or the components of the experimental equipment, time of day, time of year... you get the idea :)

In other words - if your experiment doesn't go to plan - it ain't necessarily your fault :) Perhaps that's why I was attracted to it above the other sciences... plus growing and cutting up plants, breeding, anaesthetising and counting Drosophila (hoping you haven't given them too strong a dose of ether!)...

Then for some arcane reason I decided to study computers...
