A very long time ago in good ol' Bais Yaakov I remember learning/hearing something about camels (at least I think it was camels) and their sexual habits. Something along the lines of camels being modest or private in how/where they get it on, or perhaps not modest in comparison to some other species. I guess there was some lesson or relevance in this.
Does anyone know the details of this, or (ideally) the source? It's the sort of thing I could imagine being in a rashi or something.
