it's like this:
breeding kink - nice. commonly held by straight cis women and gay cis men. beware racism ("benevolent" racism included), nationalism, eugenics
pregnancy kink - different thing (nice)
domestification kink - different thing (nice). beware racism (eg "civilizing")
"breaking biology" kink - nice, *but* remember/check for real live people who do indeed have bodies like that (examples: intersex people, disabled people, "disfigured" people, trans people)
"breaking biology by breeding the should-be-unbreedable" kink - nice, *but* don't imply that tidily matches gender/sex (example: positing all men as should-be-unbreedable)
humiliation kink - different thing (nice), but *do not* conflate with any of the above, especially without taking the other cautions into consideration; intentional combination nice, flagging such massively appreciated
pls run yr individual instance of "get him pregnant" through the above when speaking on it in any public space thx
