Sorry for the issue, the butt burn is something that happens sometimes if I am not cautious. I use the sudocrem anti-rash twice and apply it directly over the hole. Also don't let the bidet water hit directly or use very low pressure. If I use fast water it scratches the skin and then takes a few days of care to fully heal. I use toilet paper gently to absorb any extra water. Reasons for a butt burn for me are if I have runny output or I exert too much pressure on the seat or if the bidet water hits directly on my bottom.
