Censoring genitalia will be pointless as you are going to design them, unless there will be an option to not simulate reproduction which will not happen. Censoring sexual scenes, however, is more doable as you can just fade to black if your (macroscopic) organism requires physical touch. It depends on how much care the reproduction mechanics will be developed, though: if I can design something that reproduces like flatworms (i.e.: by penis fencing[1]) I would want to witness the sex.[2]
I don’t know if I skipped some posts because TL;DR,[3] but I fail to see why all of these would be relevant. The goal would be to not show any sexual and/or obscene stuff. Blurring the organs would be as effective as Japanese censorship laws. I don’t see the context in which belgium sex, necrophilia, non-penetrative sex would be shown on-screen so it’s not relevant.
