Just wanted to post here to showcase my personal (albeit short) clamping experience.
First of all, I started 2 months ago doing 1 day on 1 day off, with month 1 consisting of:
1x7mins of clamping, 5mins of jelqing and around 10 minutes of stretching.
From this, I’ve noticed that my veins became a bit more prominent, frequency of morning wood went up slightly. However, no real gains were made.
So this second month I’ve gone to 2x7mins of clamping with plenty of time in between to reoxygenate and massage (I ‘roll’ my dick between my hands like you would do when making fire with a stick).
This is then followed by again 5mins of jelqing and 15 minutes of stretching. Veins are still prominent, morning wood is still there. Haven’t measured yet, but my GF claims that it looks bigger.
Now to the real info for you guys: I typically do not see red spots or an increased girth during the clamping IF I start with clamping. However, when I start with the jelqing and clamp afterwards, I get the expansion people are talking about here. The expansion (of around ~0.8cm/0.25in) is most prominent when I sit and my dick points upwards (needless to say the hardness also fades a bit in this position). However, I also get lots of red spots, with sizes up to 0.5cm in diameter. Obviously these are blood vessels that burst/leaked a bit and they typically heal in a day or two. This leads me to believe that there is a pre-exhaustion effect (due to the jelqing) which then corresponds to a weakened state allowing for easier (or in my case, some) girth expansion.
I don’t know how familiar this sounds to you guys, but for people wondering (like I initially did) about ‘why do I not see expansion?’ it might be of some use.
