The injuries we get...

I t sounds like there is something causing chafing, maybe something not quite polished or smooth. Look closely...

I use a silicone lube, and it has made a huge difference. I found an 8.9 ounce bottle on eBay for a little under $21 including shipping. I carry a 1 oz poly bottle with me all the time and apply if needed. That has allowed me to feel comfortable in a 45mm ring without red marks. I think that the need will diminish over time.

I'm not sure its chafing - the sore bit is hidden away.

I just looked it up - the soreness is on the coronal sulcus, underneath the corona glandis. Basically on the 'neck' bit underneath the 'head' bit.

I already use some silicone lube to avoid the ring burn. Fan already!
