I could be wrong here, Eva, but I think the first two posters were refering to the harness that holds the dildo in place being leather, not the dildo itself. Certainly that wouldn't change your care tips, but it does mean that the quantity of fluids the leather is exposed to would be much less. The sturdy and non-stretchable nature of leather makes it an excellant choice for a strap-on harness, IMHO.
