[Equipment] Masks all either cause pressure sores or blow off my face

[HalfAsleep]

FYI you can’t use oil based products like vaseline near CPAP masks, because they’re silicon. FWIW a person finds out curious stuff like this at the sex toy store. They sell a lot of silicon glop. 

You can use a mask liner for the sores. Sometimes, it takes a different fit. But get the settings sorted out, and some of the mask issue might resolve itself.
