You can have some samples of your sperm frozen. The technology to enable a transwoman to carry a child is going to become a reality within your life time. Maybe in 15-20 years you can be carrying a child of your own flesh. Pretty wild, and the neat thing is that this not a pipe dream but an eventuality.

My experiance is not everyones but it can happen. I think it has alot to do with how we come out how people will recieve the news.
