A: The best position to wear the device is before erection or after slightly being erected.
(Slightly being erected means your genital is not erected yet and soft). If you use the device after erection, the organ is shrunk, and the device is dislocated.
If some of you have trouble to have small genital, try using it when being slightly erected. If you feel the organ is shrunk, just adjust the device to not be dislocated.
Some of you who wear it first may not be comfortable due to erection, but it will get used to do after wearing several times.
