No, I don't remove hair on my forearms. The only parts of my body (that show) that I shave are my chest and occasionally my face. Sometimes also lower legs during summer. I leave my armpits hairy but trim them occasionally. The carpet on my stomach I only shave if I'm... expecting company. I'm hairier than most other women, I suppose, cause of having taken testosterone for a long time. I had just stopped taking it when I started noticing back hair... glad I can prevent that! So I'm a little bit of a werewolf girl.
The hair on my forearms is not very extreme but it's clearly visible and dark brown, and it trails down on my hands and fingers too. I shaved them only once in my detransition but I didn't like it much. I realised I actually like my arms and hands hairy as they are, so I let it grow out again. It goes great with my wine red painted nails. My only issue with it is that it hurts when my little fur gets jammed in bracelets and pulled!
It reminds me of other races of which the women are much hairier than white Swedes like myself, and like that's normal for them. Perhaps I have normalised much of my own body hair for myself too. And like it's not so gendered for me now. I also think that body hair looks good on women, in general. So being hairless is not an ideal for me, and it doesn't really make me dysphoric either. Sometimes I feel a little self-conscious about it though. But then I'm afab so I know I can "lean back" on my bodily femaleness in general as a comfort, now in my transition 2.0. Had I been mtf I likely would have related to it differently.
Now that I've gone off testosterone I can expect that some if not much of my extra body hair will thin out again. But by how much and on which body parts, I've no way of knowing. I wouldn't mind it if my arm hair stays the same, and I do remember that they were quite hairy before I took testo as well.
