I feel like he doesn't know if he can children; that it's something uncertain.

Well maybe it's not easy to conceive a child for them but not impossible. Let's hope that it's "just" that. We can just assume that even with all their "sexy time" he's still not pregnant. And that's why he/they think he can't bear a child. As long as we don't see/read the proof that he's not able to, we can still hope! Sometimes miracles happen!
Why did he touch his stomach then he said he was sorry ? Is he unable to bear a child?
