unless you want to stay infertile

And also, what if some humans were ok with being infertile, if they wanted to look on their lives as something other than the perpetuation of a species? Would that even be possible? IIRC (and it has been a couple of years) the rebel humans are obsessed with the possibility of making babies. What else might there potentially be for them, I wonder--anything?

(These are longstanding obsessions of mine more than they are critiques of Butler...)
