How to Use A Glans Ring and How To Measure Your Penis

G'day,

I would like to see one of the guys that has used a "Glans Ring" for a while to show via video or photos how to measure your penis for the right size ring and how to fit the ring in place

I manually try to keep my foreskin rolled back but it never stays that way and I really want to get the "exposed glans" look

Any help would be greatly appreciated

Nude hugs
