This has to be a joke topic. Sexually Explicit? On a CONSOLE? The only explicit one I have ever seen is that sex scene between that girl and that mexican in RDR. The next one would probably be the God of War scenes.
Go download an H-game if you want explicit because consoles won't give you it.
EDIT: Forgot about Darkness 2 where you are going through the whore house and a guy is going doggystyle with a pro.
