I haven't answer your question for two reasons.
1/ You have been unable to form the question in a way that makes it answerable.
2/ It is a false equivalence to sex, sexuality and gender.
For the rest of it you have to start with a base point.
If they dig up a skeleton they will be able to give it a sex, pelvic width, hip length, bone density and DNA. Male/Female.
These are scientific facts.
Sexuality definitions are equally as easy
Attracted to opposite sex = heterosexual
Attracted to the same sex = homosexual
Subgroup of homosexual = female female attraction = lesbian
Subgroup of homosexual = male male attraction = gay
Attracted to both sexes = bisexual
Lack of attraction to any other sex = Asexual
Then you have intersex people who have asked to be left out of this.
Others may want to identify by their gender and how they feel, but a lot of us don't want or need to and identify by the sex that we are born as and do not need extra labels placed on us or those terms redefined to fit how an ideology thinks others should be seen.
It only get complex because people are making it complex.
I am quite happy to respect that people "feel" that they are a "woman" or a "man" but when you start pushing terms out like female penis, or a lesbian must fancy a transwoman or they are a transphobe then you lose all respect.
And I know that even thinking this way (in some circles) makes me a transphobe but it is a protected belief and it is held by many people.
