Do the sprites really accentuate different areas of the body? I think I just focused on the tits and bulge for all of them (Well the characters with slits don't have bulges but you know what I mean).
And yes, you should read as many of the routes as you can. It's the best way for you to understand what's going on.
There is a small part of each character's design that stands out more than the rest. Wyatt its his pecs because of the way his jacket is, Conner is more upper body/shoulders, Kamil general all rounder, Lion was more lithe looking but more so his face cause lion (^^;), Professor obviously big everywhere!, Orca looks are in line to his timidness, and Bird probably the pose and thus elbows. Examples to say that each character is done in a way that sets them apart, so they never seem to have the same build/body shape.
I will look into other routes with update(s), it may be because of choices made, but I only had three options.
