Yep, well sort of, I have "Ordinal Linguistic Personification" which I believe is classed under the umbrella of synaesthesia.
Numbers have genders and personalities, they always have for me, simple as that. Most people don't understand this, but i cant imagine it any other way. Tis just how I am.
I also see other things as having genders, the alphabet, objects (e.g. i cant think of wardrobes as being anything other than a masculine entity), and sometimes textures/feelings/senses but to a lesser extent.
EDIT: The way Id describe it to anyone curious is a "strong assosiation", something that you just accept to be. If you look at something thats yellow, your mind just instantly tells you "that is yellow", you feel it. Thats how it is.
