Measuring BPFSL with a vacuum cup?

Is it accurate to measure BPFSL with a vacuum cup? Or would it add a little too much even if you don’t create vacuum?

I’m asking this cause being uncut it’s not easy to grip, stretch AND measure. With a vacuum cup it’s very easy.

How much difference is there between the two methods?

Whichever method you choose, just be consistent in the process so you’ll have confidence that a .25” change is accurate and not a function of a different grip, less force, etc.

I am uncut, just pull the skin back and grab the glans. Unless maybe your frenulum is in your way? I had mine severed many years ago.

Is the grab glans and pull metheod “legit”? That’s how I did it before before but it stretches the glans a little longer than it naturally can be. Also read somewhere that you should grab below glans. Maybe cause of this reasons? The frenulum could be the problem. It’s difficult for me to grab without slippage and create enough pull force consistently.

I think as 32Q mentioned, as long as you’re consistent in whichever method you choose, you should be okay.

I’m uncut and measure BPFSL the same as igigi. The biggest issue that I’ve had is making sure that I’m standing up straight and my unit is parallel to the floor since the angles will give you different measurements.

Remember the purpose for measuring is not to find who has the biggest dick. The purpose is to have an accurate measurement of your gains. So it doesn’t matter if you are starting out with a 4” or a 6” or an 8” dick.

You could say that on day 1 my starting size is 0” and after x months it is 0.5” so I have gained 0.5”. You do want to have confidence that the 0.5” gains is accurate so be consistent in your measurement process.

I messed up the initial measurings cause of wrong methods. Also I’m not sure how much I stretched. That’s why I’m looking for a very consistent method. A little change of flaccidity changes everything. Think that best moment to measure is after a session when dick is very pliable and insensitive. At least for me personally cause mostly I can feel a little tension when I’m not totally flaccid. I just wanna know my unaltered current size to check my progress. Having a little upward curve makes my BPSFL the best way to measure I think.

I compared measuring vac cup with below glans grip after hanging and it looks very similar.

Other question: Does hanging stretch dick longer than actual BPSFL?

If you have a small curve you can try flattening your dick against the ruler get the true length. If the curve is too large to easily straighten, then measure NBPEL as best you can with a tailer tape or string and add that value to the thickness of your fat pad to get the BPEL. Fat pad can be measured with a hard ruler.

Remember:
BPEL = NBPEL + fat pad thickness

I don’t have an answer for your hanging BPFSL question.
