To ask if you have personally ever doubted the sex you were born into

[Chantelli]

Just that
Yabu - of course my gender and sex have always been aligned
Yanbu - I've often felt as though I do not identify with my biological sex assigned at birth

It's actually a lot higher than that.

These are statistics drawn from an article by Brown University researcher Anne Fausto-Sterling. The basis for that article was an extensive review of the medical literature from 1955 to 1998 aimed at producing numeric estimates for the frequency of sex variations. The frequency of some of these conditions differs for different populations. These statistics are approximations.

Not XX and not XY one in 1,666 births
Klinefelter (XXY) one in 1,000 births
Androgen insensitivity syndrome one in 13,000 births
Partial androgen insensitivity syndrome one in 130,000 births
Classical congenital adrenal hyperplasia one in 13,000 births
Late onset adrenal hyperplasia one in 66 individuals
Vaginal agenesis one in 6,000 births
Ovotestes one in 83,000 births
Idiopathic (no discernable medical cause) one in 110,000 births
Complete gonadal dysgenesis one in 150,000 births
Hypospadias (urethral opening in perineum or along penile shaft) one in 2,000 births
Hypospadias (urethral opening between corona and tip of glans penis) one in 770 births

Total number of people whose bodies differ from standard male or female one in 100 births
Total number of people receiving surgery to “normalize” genital appearance one or two in 1,000 births

Ambiguous genitalia at birth occurs in about 1 in 1500 to 2000 births. This is where they ask a specialist to determine appropriate gender. The parents don't always agree.

As a child I was very much what they called a tomboy. I was ever one for dolls or makeup or girly clothes. I played football with the boys. I was 16 before I realised that boys were physically attractive and that they fancied me. I was definitely a woman.

I wonder if I was growing up now, whether I would have thought or be told that I was actually a boy?

This is an interesting question.
When I was 4 till about 8 I genuinely felt wrong like I was a boy not a girl. I wanted to be a boy, i had my hair short, dressed like a boy, was a tomboy, rebelled against anything feminine even tried to pee standing up. My mum caught me and knocked ten tons of shit out of me and threatened all sorts if I ever did anything boyish again. So I repressed it really.

I still couldnt bring myself to do anything feminine, hated dolls and dresses and when I was a teen refused make up and looking pretty much to my mothers disgust.
I had crushes on girls but when I was 14 started fancying lads and by 21 had children

Instill not feminine now although I do like dresses and a little bit of make up now but I'm not into girly stuff.

I do wonder of I had been allowed to carry on as I was would I have been trans. I felt so unhappy as a girl

No you certainly wouldn't. It's not about conforming to gender stereotypes.

I was a tomboy and happiest playing with 'boys' toys etc. but didn't doubt i was a girl. Just one frustrated with not being allowed to join the footie team or go to scouts.
If I was as aware of trans kids as my children are - I would still have been happy as a girl. I never wanted to be a boy, never thought that was better, in fact I almost pitied them for being such idiots sometimes...
I'm a lesbian.

I would say that I have never doubted my biological sex but have often chafed against the expectations of how my gender should behave. That didn’t make me question if I was really identified as the correct sex, rather that I hated the fact that gender roles were a thing, rather than letting people just be themselves.

@WeeMadArthur has expressed it very well.

I would add that I think biology is fixed - the body you are born with IS the right body - it’s your body so it cannot be the wrong one.

Gender is far more fluid and changeable, and I think that most of us do not fit completely into either of the gender stereotypes of male and female. I think these stereotypes are harmful, even toxic - where little boys are told they can’t play with dolls, for example, or little girls toys are all pink, or where t-shirts for boys say ‘Future engineer’ and the girls’ ones say ‘Little Princess’. Where men are assertive but women are bossy. Where men are articulate and authoritative in their speech but women are loud and strident.

I believe that women and girls need the safety and dignity of single-sex spaces, and that they have the right to assert these boundaries without being told to ‘choke on my girl-dick’ or ‘die in a grease fire’.

I believe lesbian women have every right to refuse to have penetrative sex with a penis-having person, even if that person has declared themselves to be a woman and a lesbian.

I believe we need to have sports divided by biological sex, and I believe that so-called male athletes who have mediocre results when competing against other biological males, and the start winning awards and records when the identify as female, are cheats, nothing more, nothing less. I believe it is unsporting to allow someone with all the physical advantages of growing up male (muscle mass, bone density, lung capacity, strength, endurance) to compete against biological women is to destroy women’s sports, and, in some sports, will lead to serious injuries - cage fighting, boxing, rugby, for example.

I believe that women still need the support and positive discrimination (that is the wrong word, but I hope you will forgive me) in society and the work place, because we are still not equal to men - there is still oppression and discrimination against women, many micro aggressions, not enough women in the top jobs, poorer promotion prospects - and letting penis-havers into jobs/opportunities that are specifically for women, harms the progress of feminism and women’s’ rights.

I believe anyone who rapes a person with their penis, does not, and never will belong in a women’s prison, and their crime should not be recorded as a woman’s crime.

I believe it is child abuse to give a prepubescent child puberty blockers that may well render them infertile, and set them on the path towards ever more medication and surgery. Just let kids be kids - let them play with whatever toys they want, wear skirts or trousers, pink or blue or whatever colour they like without judgement or teasing.

Always felt like a woman although I’m not very girly in general.

I have periods of gender dysphoria, much rarer now than when I was younger, where being seen as my sex caused me distress, where parts of my body felt alien, I had phantom sensations, and generally felt more comfortable being seen as masculine. I have fond memories as a teen wearing a wrestling hoodie having little old ladies say 'thank you, young man' when I helped them.

For me, it wasn't about gender identity though. I view gender in a more sociological way than individualistic and have never really understood how gender is meant to feel. For me, my dysphoria is part of my PTSD. I am an unwanted daughter, a lot of my mother's abuse towards me was framed as being because I wasn't born male as she wanted and was failing at being the right kind of girl for her too, and I felt safer being as not like my mother, and what I was failing at, as possible.

Now it's far milder, I still sometimes get it if I feel any attention or focus on my chest (I wear shirt layers to avoid that), it's like a threat response, like feeling the hairs on the back of your neck when someone's watching you , I can start feeling pressure and disconnection from my chest. I have to be in a really bad place before it moves beyond that.

No because I feel like it doesnt matter what my sex is.

My sex is female and I identify as female. Have never felt I could be male. I am probably equally masculine and feminine when it comes to gender stereotypes so I wouldn’t describe myself as ‘feminine’.

To address my problem with this I can only think asking my pronoun to be 'they' is my only real, feminist option.

No. Gender, however you define it, is essentially a load of sexist bollocks & the only real, feminist option is to get rid of it. If you use ‘they’ because you don’t match feminine gender stereotypes, you’re strengthening those stereotypes. If you stick with ‘she’ because regardless of the stereotypes your sex is female, you’re fighting them.
I’m a lesbian with a Grade 1 haircut, a techy job & a total lack of interest in high heels & makeup. I know I’m female because I have a vulva & no Y chromosomes. That’s all it takes.

I never felt like I fitted in with other girls. I related more to "boy" stuff.
