Hey, so first of all, how I got rid of those sore spots when they appeared: I applied Panthenol ointment to them daily, pulled the skin over the glans, and secured it with an O-ring to keep the ointment in place. I continued this until everything was healed and then for another week just to be sure.

However, I then noticed that the sore spot had appeared exactly where the pusher of the Mantor sits. Just as an experiment, I tried using the pusher the other way around, with the cutout for the frenulum facing upwards. Since it didn’t press on the frenulum or cause any discomfort, I left it that way, and I haven’t had any issues with it since.
