You are, by your own admission, a trans woman. This means that you were born with a penis and testes, and without ovaries, a uterus, a vagina or the genetic coding to grow natural breasts during puberty.
The women on this site are acutely aware of their own biology.
We remember what it feels like to start growing breasts, when the slightest knock to that area would cause a sharp and distressing pain.
Virtually all of us have at some point menstruated. We remember when and where we were the first time we went to the toilet and saw blood in our underwear. We have had to get to grips with the different types of sanitary protection. Many of us have experienced severe pain each month. Many of us have experienced flooding, often in an inconvenient place, requiring a change of clothes.
There is an entire board on this site dedicated to women who are trying to conceive, many of whom take their temperature every morning and use ovulation test strips to figure out when they are ovulating in order to time sex for a successful conception.
There is another board dedicated to pregnancy, where women who are pregnant are talking to each other about scans, nausea, hyperemesis gravidarum, what it feels like when their babies kick inside them, gestational diabetes, pre-eclampsia, what to pack in their hospital bag, how to prevent stretch marks and so on.
There is another board dedicated to infertility, where women who have so far been unable to conceive are discussing their blood test results, their antral follicle counts, NHS wait times for IVF, the best/cheapest clinics abroad for those unfortunate enough to live in an area where the NHS will not help them at all, sharing stories of their own trauma resulting from the fact that their ovaries and uterus do not seem to want to fulfil their biological purpose.
There is a board dedicated to miscarriage and pregnancy loss, where women share their pain at having lost very much wanted babies, where they comfort each other, where they sometimes ask for practical advice about when to go to the EPU or when to try again or even how to try and catch a 7 week embryo as you miscarry and bring it to the hospital for genetic testing. They are discussing which doctors might be able to help them, how much it costs to get private treatment, what medication they are on, and how to get prescribed progesterone when their GP is clueless, unsupportive and overworked. There are also women on there who have had a full term stillbirth.
There is a board dedicated to contraception, where women ask for advice about pills vs coils vs implants because nothing has worked well for them, or complain about the fact that they want their tubes tied but no doctor will agree to do it in case they change their mind about wanting children. (They apparently know their own minds less than 10 year olds who want puberty blockers.)
There is a board for pregnancy choices, where women with unwanted pregnancies seek advice about getting an abortion.
There is a board about childbirth, where women are discussing the pros and cons of an elective C-section (which involves cutting through multiple layers of abdominal tissue and leaves a permanent scar on each layer) vs a vaginal birth (which might result in forceps, ventouse, an episiotomy or a tear right through from her vagina to her anus, leaving her doubly incontinent). Or they are asking for advice about whether to agree to an induction, which makes labour more difficult and painful and more likely to result in the interventions described above, but they have been given dire warnings about the risk of stillbirth increasing if they do not agree to be induced. Or they are discussing their very traumatic births which have left them physically and mentally scarred, with little or no support from the NHS.
There is a board for women going through the menopause, many of whom are experiencing debilitating side effects which ruin their enjoyment of life but are unable to get HRT due to the shortage (which is exacerbated by the fact that these drugs which women need are also being prescribed to trans women who merely want them).
All these women are very acutely aware of their own female biology.
You are not aware of any of these things because you have not experienced them and never will.
I do not wish to be unkind, but this is what it really means to live as a woman, which is why so many women on Mumset are unmoved by people who were born male claiming that they are women because they identify as a woman and love as a woman.
And it comes across as extremely arrogant to say that you are more acutely aware of the differences in our biology than we can possibly imagine. We don't need to imagine it. We are living it. It is you who cannot possibly imagine it.
