Cool. First off, mostly personal preference, the game feels a bit sluggish. I had this problem with the first one too. I don't know anything about the game engine, but it might be a good idea to speed up most of the non-sex animations by 10% - 20% or so if possible.
Secondly, if enemies are going to be as low as they are, a crouching melee attack would be a good idea.
It's entirely up to you. It's your game, so you should be free to make it however you see fit. I love pretty much every single one of your games, so keep up the good work.
