Well, for me, it's more a matter of finesse than wierdness.  If a tentacle monster used a bit of foreplay ravishing me, I'd have more fun than if a comely member of a gender my charecter found atractive just thrust in.<br/><br/>If there's something that grosses me out in the hentai department, it's decay.  Slime can be kind of cool, and strange animate objects/cybernetic devices, but keep your zombies to yourself.  ;)
