Hi Igigi! I’m also doing the ultrasound method. I don’t have a progress report thread and I no longer keep perfect logs like in the beginning, but I’ve been doing it for about 1,5 years now. Before that I was not new to PE but had done some PE on and off for some years. I’ve gone from 23 cm pre-BPFSL to 27,5 cm pre-BPFSL. Max ever post-BPFSL is 28 cm (measured from the pubic bone but on the left corner of the penis). Sometimes I switch to IR pad, and sometimes I’ve had to do other things because of blisters, but the base routine has been extender and then OTL hanging with ultrasound.
Best of luck.
I sometimes check in to keep an eye on your log.
