// FAQ
Good to know
Why does size actually matter?+
Too tight increases breakage risk; too loose increases slippage risk. A snug, correctly sized fit is the single biggest factor in reliability, ahead of brand or material.
How do I measure girth?+
Wrap a soft tape (or a strip of paper, then measure the paper) around the shaft at its widest point while erect. That circumference is your girth measurement.
