I used this sheath twice since receiving it 24 July 2023. The 2nd use I wore it to bed overnight as it was fairly comfortable the 1st wear for around 2 hours the day prior. When I woke in the morning, I felt a little discomfort under my helmet, so I took the sheath off. I was a little red all under my corona area of the remainder of my cut foreskin area (under my glans). I didn’t put the sheath on after my shower as I was wary of what it was doing. The next day, the remainder of my cut foreskin area was more marked than the day prior and now I noticed my frenulum was also damaged. Today is day 4 since wearing it and over the past few days I’ve had to place an antibiotic cream around my remaining cut foreskin area including all over my frenulum as it had almost cut right through my frenulum. The frenulum is my main concern as I don’t want to lose such a vitally sensitive part of my remaining cut foreskin area & luckily it’s slowly slowly healing, but extremely tender. The ridge of the sheath needs to be angled better to mimic the glans shape on most guys , or shaped downwards not to interfere with this area of the area to prevent it cutting into the tender frenulum some of us cut guys still have (thank goodness). If I wear it again after my frenulum heals, I’ll need to pull the sheath down past the ridge of my corona glans area so it won’t irritate my poor frenulum again (or will I wear it again …?? 🥺😳)? I’m pretty wary of it I must admit which is a shame for such an expensive item (in $AUD/USD currency exchange).
