If you want to worry about something, worry about the fiance touching her, or us not getting a sex scene between Mei and Yuzu at the end of the manga.
The kiss with Amamiya sensei was enough to turn some people off from the anime, I dont think Saburouta would go THAT far. XD
And yes, we would have had MANY sex scenes if it werent for Yuzu wussing out.. (GO YUZU! :D)
