Ok, so I've gone to a few sites and am looking to get a steel cock ring called a gland ring (it goes up towards the head and snugs up to where your circumsized, is actually really cool)... anyways they have a few different sizes starting at 1.0, 1.1 and , 1,25 and maybe another one under the 1.25 and after using their calculator that measures your glans area, the Corona flacid as well as the glans area while erect.....i guess the math goes the average of flacid vs erect and also take into account the Corona...i dunno, but with 4.2 flacid and 5.4 erect with a4.6 Corona I'm getting a diameter that requires a 1.63 glans ring, which seems way out of range to me... anyone else have glans rings and can help decipher this for me? Thanks
