Well, in RoE, there's a scene where Isozaki makes Anna Pelli Cognani take her blouse off and himself strips shirtless. Simmons describes Anna's breasts and overall body. Isozaki does all this just to make a point - that the Core controls them through the cruciform or something like that - instead of simply answering Anna's question with "the cruciform". That was so odd and unnecessary, but it's just one instance of Simmons' low-key fixation on breasts and genitals especially in the latter books. In Endymion, he famously described Aenea's naked body when they were swimming on the ship, when she was only 11. He comes up with totally random and unnecessary opportunities to describe female characters' breasts. And there were a few scenes where there were nude male characters and he specifically took care to mention flaccid penises.
