Generally, you should use a cloth tape measure to measure dick. There are instructions online if you look.
Also, 8 inches to the hilt is often not pleasant, so work with your partner and learn how deep your sigmoid colon is, and take it slow. Big ol’ dick slamming into a wall is not fun unless you are very particularly into it.
