Tgirl,dm me if I'm fuckable

Pretending like biological sex isn't real is ridiculously stupid. You say that you believe in science but you think that humans are the one primate to not have two sexes?

Also stop using intersex people as pawns, it's actually offensive

a) I'm intersex. what is with tumblr anons and assuming I'm not in a particular group I talk about with experience? Ffs. First ableism now this.

b) Biological sex *isn't* real. It's a model. Much as species aren't real. Yes, there are "two sexes", but sexual characteristics don't form two pillars on either end they form a reverse bell curve, with much variation in the middle.

c) I don't believe in science. I know science. I am a scientist. which means I know it's not as simple as "two sexes" for any organism whatsoever.

nice try.

Sex Questioning Flag

Sex Questioning is a process of exploration by people who may be unsure, still exploring, and concerned about applying a sex label to themselves for various reasons.

Colors from this flag by @protego-et-servio​ using -genital flags format, however sex questioning could be more than just genital, could apply to question your genotype, karyotype/chromosomes, gonads and so on. Not always questioning if they are intersex but could also altersex, perisex, parsex or protosex.

Term of the day: Altersex

Altersex refers to a person who is not intersex, but for some other reason does not fit the male/female sex binary. This can include:

People who were not born intersex, but have undergone hormone replacement therapy or surgery that affects their biosex

People who were not born intersex and have not undergone any medical procedures that affect their biosex, but have a mental body plan that incorporates such modifications

Fictional characters who have a biosex that falls outside of human anatomical possibilities

The term was coined by farorenightclaw largely to describe fictional characters, but specifically to have a word for people who are not intersex, but also cannot be described as perisex.

People who have undergone medical procedures that affect their biosex may not identify as altersex, but also male, female, or nonbinary (in the case that their gender is nonbinary, and they consider their body to be nonbinary as an extension of that)

The flag was created by @pastelroswell with the following meanings:

Mint green is commonly associated with specific altersex identities, like angenital and salmacian. And also because green represents abundance and growth: abundance of possible body types, and growth as in people who physically transition to “grow” into their true bodies.

Blue represents fluidity, for bodies that have fluid sex characteristics. White represents transcendence, as well as bodies with no sex characteristics. Purple represents the alternative, non-traditional nature of altersex bodies. Reddish pink represents sex characteristics.

Contraceptivo unissexo á base de plantas impede fecundação e não possui efeitos colaterais

Três biólogas da Universidade de Berkeley, na Califórnia, relataram em um estudo para revista PNAS uma forma de contraceptivo de uso inter/unissexo que, basicamente, acaba com as forças dos espermatozoides. Elas o fizeram por meio de uma substância utilizada na Medicina Tradicional Chinesa, chamada pristimerina, conforme informações da Super Interessante.

Chamada de “camisinha molecular”, a substância é encontrada na planta Tripterygium wilfordii, cuja principal qualidade é a capacidade de agir como progesterona, um hormônio essencial para a reprodução humana.

Em pessoas ovari, a progesterona é conhecida por regular, com a ajuda do estrogênio, o ciclo menstrual. Contudo, ele tem outra função importante, que é servir energia para os espermatozoides conforme eles tentam romper a parede do óvulo. E é por isso que o óvulo costuma manter um estoque de progesterona, para que as células dita masculinas consumam o hormônio e tenham forças para acelerar e penetrá-lo.

A pristimerina age da mesma forma, só que tem efeito contrário: quando o microgameta a utiliza, sofre reações químicas que o inutilizam. E é por isso que, quando em doses suficientes, a substância pode agir como um anticoncepcional 100% natural, sem efeitos colaterais relatados e, mais importante, próprio para qualquer pessoas de qualquer sexo. (endo-, inter-, alterssex)

Um bônus sobre o método é a questão ética, uma vez que ele evita a união das células, impedindo-as que formem um zigoto. Logo, ele é isento de críticas religiosas, que argumentam que a vida começa logo na fecundação.

This is an excellent article on how biosex is not binary and the various ways it relates to gender. Summary:

Sex is composed of a number of traits that have more than binary variations and do not always all align

There is no “essential” sex and sex can change

Gender is impacted by sex and sex is impacted by gender, allowing the interpretation of gender as a trait that comprises sex; like other sex characteristics, it is not binary and does not always go with the same set of other sex characteristics

Biological sex differences exist outside of society, but the way we interpret them is socially constructed: therefore sex is a social construct

Women are oppressed because of sex and gender, not one or the other

Sexes. They’re called the sexes, dumbfuck.

No, just no.
