I know the felling, in my situation you much kinda deside what you want, to get dignosed with ->-bleeped-<- and get your gendermarked change you would say goodbye to options like sperm donation or adoption.
I know a couple of transpeople who has kids but its all biologically and been in there past, I never heard of anyone who got thought adoption or with a dona, even when I know some who tried.
its not 100% imposible nothing is, but I would say in mu current situation its like 90% imposible if I dont go "biological/traditional way" and I wont cause pregnacys creep me out, even seeing other womens being pregnant are kinda wierd for me.
as it said before I wish I had the option, I grew up thinking "why even bother I cant get marrige and I cant get children" when people asked me I said so because it was too complicated to explain all the details,
that I in fact didnt want to carry a child but I wanted to be the father".
I do feel its much a "either you go off homones and get pregnant or you dont have children at all" choice, and I understand those who really really want children more than anything ells in there life that they do so, But for me its way too painful to go tought. I thouhgt maybe I could help suporing a child for one of my friends or something.
