The FitKit is not only a great way to find your perfect myONE size, but whose to say it can't also be a fun research project. Hey now. Here's some tips and tricks to using the FitKit:
You'd be surprised how many people use their FitKit while not fully aroused. Here's where that great magazine, video, or helpful friend can come in handy. Not being fully erect could lead to the choice of condom being a little too tight, and tight is bad when it comes to putting things on your penis.
When measuring your circumference (the "wrap around" step) don't wrap too tightly. It's not like you're trying to strangle a garden snake. You're aiming for an accurate but comfortable measurement so hold the FitKit gently in place.
Blessed with a large foreskin?
Add a letter to your length code to ensure you get extra length in your condom fitting. For example, length code 'E' becomes 'B', 'B' becomes 'S' and so on. You can see those codes right on the FitKit.
Concerned about tightness?
Choose the next number higher than your measurement to get a fit that's a little looser. For example, width code 55 becomes 66, 66 becomes 77 and so on. You can see those codes right on the FitKit.
Close to a line?
If you're close to one of the measurement lines, then just select the longer or looser code.
Most guys are a pretty uniform circumference along their length so doing the wrap around measurement once in the middle gives an accurate width code. If you're not like this then feel free to take multiple measurements along your length and use the average.
