There's no need to feel uncomfortable. Just treat your slaves with the fullest respect. :)
Anyway, yes, I've actually thought about implementing a female MC choice in the future (and also male slaves). Especially if it becomes a popular request.
I've already done some groundwork regarding this but it's not my top priority right now. It will require a completely new chunk of text too that'll follow the gritty and realistic feel of living as a female in Ikaanos.
