Blood is in Infinity War when Tony is stabbed by Thanos blood comes out of his mouth same for Coulson when stabbed in Avengers also I remember Cap bleeding after Bucky shot him in Winter Soldier. Body dismemberment Bucky, Klaw losing his arm, Thor losing an eye, Nebula in Infinity War being tortured by having her body ripped apart to name some. Kinky Sex the Ravagers went to a robot brothel in GOTG Vol. 2 that's kinky their robots and also Wanda's banging an Artificial Man the MCU has a fetish for Robot love what can I saw also as Howard said once you Duck you're out of luck. Frontal Nudity have you not seen Thor? Marvel does need to work on their homosexuality representation but it's not like the XCU was much better.
Small Children torture well Gamora saw her people killed in a genocide and Peter was beaten to a pulp in Homecoming he's a kid (More Blood)
