I feel like as a trans man that want biological kid(s) with my trans girlfriend, I need to be the one carrying the baby, if there literally isn't any other option, I would be willing to just deal with the dysphoria and carry the child (the want of having a child will be stronger than the dysphoria) However my girlfriend has said that me being pregnant would cause her dysphoria (not dysphoria over her not being pregnant but over the fact that she got me pregnant) we do both want bio kid(s) so what should I do? Is there any way we (me and her) could solve this?

Edited to add: what could I say/do to start a conversation with my girlfriend about this and come to a conclusion on what to do?
