Maybe I am misunderstanding, but my male character is described as having tits. My character is a herm, so maybe that does something, but I think maybe it's just a size thing. Have you tried upping them to a B or greater (you can reload after) and see if it uses a different description?
I want flat, and A-cup, male-identifying characters, with low or zero tone, to be able to use the feminine chest descriptors, instead of it always mentioning "pectoral muscles" and "pecs". Flat-chested female-identifying characters, with low or zero tone, do not have "pectoral muscles" or "pecs" in their appearance information. "Pectoral muscles" implies there's some visible muscle mass there, but flipping the gender option removes all mention of muscles.
Let guys have "girly, soft" chests.
The screenshot was to show that not even having breasts in the parser will override "pectoral muscles" in appearance information, unless the breasts are above a certain size.
