I have had many procedures/events that helped define my womanhood... things like..
dressing up as a woman for the first time
getting my ears, navel and nose pierced (3 holes in each ear)
shaving my legs and armpits
getting a pedicure and manicure
starting hrt (I remember the feeling of getting the first injection.. almost feeling my estrogen entering my body)
growing breasts (HRT was kind to me D cups) and actually requiring to wear a bra
getting my feminine tattoo on my lower back (I want another tattoo)
waking up after SRS knowing i finally have a vagina.. 5 months post-op
but there are two events and these sound very silly after the impressive list above,,,
The other week, I had to attend a work function with supplier and I wore an evening dress.. and with this I had a wear a strapless bra and this stupid bra, kept on poking me and made me very uncomfortable..I dunno why, as i have worn this type of strapless bra before.. My roommate who is g-girl.. said well woman suffer for beauty.. welcome to womanhood sister. She also said.. to make me feel better as I was not a happy camper.. try having the same bra problem and period cramps on top of that..
the second one, during SRS recovery, its a good idea to use pads to line your panties, and I needed to change mine.. and I run out..(had not got around to the shops). after panicking my roommate gave me one of hers.. She just said welcome to womanhood... this is what we go through every month.. this one i think connected me to the sisterhood..
Those two events which I think woman suffer from everyday, I think defined me and said now you are a woman.
I have found, that sometimes to look good.. and yes my breasts looked fine in that bra.. woman do suffer some comfort issues...
