>>My base is wider than my gland, where do u find the best position for the retainer band to stop slippage.<<
I personally prefer to wear the retainer band at the base of the shaft. However, if the base of the shaft is larger in circumference the best way would be to take the girth measurements at the base, mid-shaft and behind the glans for the custom tapered sleeve. This will give you an even fit along the entire shaft. You can send a message to the support email at firstname.lastname@example.org to work out the sizing.
