Morrissey has never discussed exactly what his songs are about - not even in his Autobiography does he touch on the subject - so, absurd as it sounds, pastries could indeed be the subject matter of that particular composition. In art we tend to apply our own interpretations, so the fact you think his every lyric concerns sex is more a reflection of your own frustration in that area.Sure it is. Just like “I Can Have Both” is about buying pastries.
