I do the reversed kegels

I've always done them while edging, etc. Really expands the penis to it maximum.When I measure, I kinda half way do it as in relax instead of really pushing, because it feels natural.
I did a session today, and I can confirm the 17.5cm BPFSL multiple times, HOWEVER, I felt the need to adjust the ruler, losing around 0.2-0.3 cm at average. By adjusting the ruler, I mean I now measure it like you do with the ruler laying flat on my penis pressed in. I used to measure it like you do in the BPFSL and BPEL pics (which gains me around 0.2-0.3 cm), but it feels too uncomfortable and would often give too many different measurements. By measuring with the ruler on top, it would always stay at the exact same position...
So sadly, I am at 17.2/17.3cm BPFSL, but I still gained the same amount from 5 days ago.
I also measured BPEL today and I have decided to cut out the measuring tape for a few reasons:
* Hard to see exact length due to it dropping down the glans
* Often had to re-measure 10 times to get an accurate measurement
* Clumsy
I now just use a straight light thin plastic ruler, and suprisingly enough, it gave me
6.6" (just like yesterday, so it's confirmed. Gained 0.1" from last time I measured). I did measure with the measuring tape just to see how much length I lose using a straight ruler before I ditched it, and it wasn't much, about 0.2 cm (more if I would really dig in the pubic bone, but digging TOO much is cheating to me).
I won't update BPFSL gains here before I reach 18 cm.
