Child Blocker?

I have been thinking a lot lately about how I'm not going to ever be able to get pregnant. It's not that I'm not able to it's just that if I did with my 25% lung function I could die and I don't think that would be very good. But all joking aside I wonder if this is going to affect a guy's decision to date me or marry me. Will it make him upset that he woulnt get to see his child grow inside me? Will he be uncomfortable or upset that we will have to borrow another woman's body to grow our baby? I only know one thing for sure. If he is not okay or accepting of this limitation in my life, then he doesn't deserve to be in it and he is not the man for me.
