Firstly, some way to become immune to Bleeding. While there are weapons Hiro can use that don't cause bleeding, most enemies seem to do some level of bleeding, and there's nothing more irritating than being halfway through wrapping Hiro around an enemy in various positions only to get a "YOU'VE BLED OUT, FIGHT OVER!" pop-up.

On that same note, it'd be really neat if there was a reliable way to goad enemies into missionary. Is Hiro is lying face down they wrestle him, yeah, but if he's on his back, they just sit on his face then usually do 69ing. Even just lowering the chance of it so that enemies might do other stuff; missionary wrestle, footjob stuff, whatever, just something other than 100% face sitting. These would both just be lovely to see.
