Simply sharing my experience with trying to figure out the appropriate size Jail Bird to order, if I actually do.
Ordered MM sizing rings.
Prior to their arrival I tried to eyeball the diameter of my flaccid shaft; 1 1/2 inches.
Created a thin short measurement device out of food box carton, to measure flaccid length of penis. Varies between about 2 1/2 and 3 inches.
Received rings.
Chose what I thought was the appropriate sized base ring (1 3/4), as only one fingertip fit behind. Later discovered I could press one of my testicle out, so dropped down to 1 5/8.
Seems small but can still squeeze a fingertip under. No problems wearing ring; may have had minor abdominal discomfort at first.
For the shaft diameter I found the 1 1/2 ring would have been way too big; so much for eyeballing it. Even the 1 3/8 fit loosely, with visible gaps. The 1 1/4 fits snuggly.
Have been wearing the 1 1/4 and 1 5/8 rings on and off the past couple of days. Went to bed with them on, to see how my body responded.
Woke up with uncomfortable but not painful erection about 1 AM. Took the rings off at some point. Have worn them most of the day. No obvious problems.
The 1 1/4 stays in place on my shift, may be a little too small, but 1 3/8 leaves large gaps.
The length of my flaccid penis with the shaft sizing ring on is about 2 1/4. The ring helps create a better point to measure from, because of attachment of my scrotum; don't need to subtract 1/4 inch.
So my challenges will be my small testicles and scrotum, and perhaps my between sizes shaft.
I trim my pubic hair, but don't shave.
Current job doesn't allow for me to wear it 24/7, so might not have chance for body to adjust to wearing long term.
Penis definitely a grower, so plenty to restrain.
Penis is pencil shaped, though with defined coronal ridge. Considered the KINK3D Cobra, but don't have the appropriate shaped penis for it.
