For a long time, I felt very jealous to my cis friends because they can conceive children. My one friend has had 3 children, who are pretty darn awesome kids. And my other friend wants to try and have a child fairly soon. Next January, but she just moved so she needs to get the new house set up and money and what not.
Like I said, I felt jealous when I hear these stories from them or see pregnant women. Like the OP, I do feel like I have missed out. Or will miss out once I go through HRT and eventually have SRS/GCS.
"I'll never be able to have kids." was a thought that would just torment me a lot. Because I adore children.
BUT!!!
Since my niece was born four years ago, I have been taking care of her, more or less, full time since my sister went back to work. So the feelings of motherhood and having children has been both accerlateated and leveld off when I take care of her. I love her, but I really want to have kids kind of feeling? if that makes sense?
But I was taking with my therapist about this during my last session, and it helps to air these feelings out, because it gave me a chance to come up with ideas on how to become a mom.
Adoption! Surrogacy! Marrying a guy with kids! etc! But I think I would choose adoption. since I am adopted as well. It always felt right adopting kids even before I figured out I was trans. It made sense to me.
So really it depends on the day for me now. I feel okay knowing I can still be a mom one day. Even if I cannot have kids the way I want, it wouldn't make my motherhood less important or make me less of a woman.
