With the exception of (which is ONE specific company) I've never seen the bitten apple used widely as some short of metaphor for "sex shop", including in UK and France.
I'm sure one can find a few examples, as a bitten apple makes sense (like lips do, tits, handcuffs, the letters "XXX" and other such symbols). I doubt one can find many, much less it being the "de facto" sex shop symbol there.
