The girls are awesome, but the guys get boring. Add some size/style adjustments to their wangs and body types and offer at least something to break it up a little, facial hair, hair color, age, glasses, just about anything subtle would go a long way with the wide range of girls.
And one other very awesome addition would be the ability to do pull-out cumshots from any sexual position, even the Oral Addictions sets already in place. Maybe kinda like Cherry Dolls where when the time comes, you have a choice, in or out.
Just my 2 cents, love the game.
