Created by Saiv46 as asnwer for "When Binary Code Won’t Accommodate Nonbinary People" article.
Revision 2: Thanks @wizzwizz4@fosstodon.org for feedback and help
This format created compatible with databases storing user's sex as boolean or uint8. Numbers here are represented both in binary and decimal.
Tillie-code consists of three components:
- 0b00000XXX - Gender identity
- 0bZ0000000 - Non-disclosure flag
- 0b0YYYY000 (optional) - Sexual identity
Gender can be stored in 3 least significant bits of traits:
- 1 - Masculitiy
- 2 - Femininity
- 4 - Fluidity
Masculity and femininity can be both or neither specified for bigender and agender respectfully. Adding fluidity trait specifies genders that can transition or fluid into any.
| Code | Fluid. | Fem. | Masc. | Gender |
|---|---|---|---|---|
| 000 (0) | No | No | No | Agender |
| 001 (1) | No | No | Yes (+1) | Male |
| 010 (2) | No | Yes (+2) | No | Female |
| 011 (3) | No | Yes (+2) | Yes (+1) | Ambigender |
| 100 (4) | Yes (+4) | No | No | Agenderfluid |
| 101 (5) | Yes (+4) | No | Yes (+1) | Male-fluid |
| 110 (6) | Yes (+4) | Yes (+2) | No | Female-fluid |
| 111 (7) | Yes (+4) | Yes (+2) | Yes (+1) | Bigender |
That should be enough for 99% of people to represent their genders this way. Note: This should not be viewed as list of definite genders, but as list of umbrellas of genders to be under.
Sometimes people may choose to NOT disclosure their gender identity.
In software it should be respected, and value of 10000000 (128) should be used.
Sexuality is stored from 4th up to 7th most significant bits, leaving 4 traits:
- 1 - Femininity-attracted
- 2 - Masculitiy-attracted
- 4 - Attacted by other things
- 8 - Demi
For sexuality, there may be difference for some genders - they labelled with (F) or (M).
| Code | Demi | Other | Masc-attr | Fem-attr | Sexuality - (F)eminine / (M)asculine |
|---|---|---|---|---|---|
| 0000 (0) | No | No | No | No | Asexual |
| 0001 (1) | No | No | No | Yes (+1) | Gynesexual - Hetero(M) / Homo(F) |
| 0010 (2) | No | No | Yes (+2) | No | Androsexual - Homo(M) / Hetero(F) |
| 0011 (3) | No | No | Yes (+2) | Yes (+1) | Bisexual |
| 0100 (4) | No | Yes (+4) | No | No | unspecified (ambiquity-attracted) |
| 0101 (5) | No | Yes (+4) | No | Yes (+1) | Gynesexual (exclusionary) |
| 0110 (6) | No | Yes (+4) | Yes (+2) | No | Androsexual (exclusionary) |
| 0111 (7) | No | Yes (+4) | Yes (+2) | Yes (+1) | Pansexual |
In second half, entries are skipped to avoid repeatability. You may probably add "demi-" to sexuality of first half if unsure.
| Code | Demi | Other | Masc-attr | Fem-attr | Sexuality - (F)eminine / (M)asculine |
|---|---|---|---|---|---|
| 1000 (8) | Yes (+8) | No | No | No | Aceflux |
| 1011 (11) | Yes (+8) | No | Yes (+2) | Yes (+1) | Semibisexuality |
