Study participants used a range of terminology to discuss feeding their babies from their chests. Six used the term breastfeeding, four spoke of nursing, three preferred to say chestfeeding, two used both breastfeeding and nursing, two said it did not matter, one used feeding and nursing, and one used feeding and mammal feeding
from the paper linked upthread. Note breastfeeding and nursing came before chestfeeding for the transmen respondants.
Personally I found the paper interesting. My loathing of my chest/breasts saw me diagnosed with body dysmorphia. I used to bind/starve myself. The advice from my last psychiatrist was to stand naked in front of a mirror twice a day and tell myself how beautiful I am. He was patting my thigh at the time. Spoiler alert, it didn't work. Still hate my breasts.
Some of the themes in the paper were thought provoking. Feeling they had to lie to get surgery (re wanting children), breast tissue growing during pregnancy/immediately afterwards depending on the type of surgery carried out (a possibility they hadnt been informed of), wanting to go back on hormones whilst still feeding etc.
Of the nine participants who had surgery before pregnancy:
four participants said they had not considered pregnancy or lactation at the time of surgery.
And
Participants did not discuss future infant feeding choices with their surgeons in consultations prior to surgery, and no surgeon brought up the topic.
In any of the 9 cases which seems somewhat problematic. I can understand the participants failing to mention it but you'd think the medical professionals should have.
Providers need to be aware that the act of breastfeeding or chestfeeding is not necessarily perceived as feminine by their transmasculine clients.
Obviously can't speak for anyone else but I didn't feel feminine when breastfeeding. Female perhaps but definitely not feminine. In fact several conclusions they draw would apply beyond transmasculine people, I.e random breast grabbing by "helpful" hcps trying to latch babies.
