Godzilla,
I also agree with the value of stretching and do it before anything else.
I also like the effect that an ADS has on my flaccid helping it to stay longer. I have a hard time saying what my flaccid is because it is never the same. It fluctuates between 5” and 6” BPFL measured at various times through out the day.
Look through some of the clamping threads. There are several really good threads going into details on the do’s and dont’s of clamping.
In short, most of us who clamp will use some form of wrap or padding between the clamp and our unit. I use a infants sock with the toe cut out and rolled up. This helps make the size of the clamp a better fit and just as important prevents me from getting pinched.
Your girth is about the same as mine right now. That clamp should fit you fine while using some type of wrap. Put the wrap and the clamp on, with the hinge @ 6 o’clock (top of shaft is 12 o’clock). Tighten the clamp down just a little to keep it in place, then do whatever you need to get hard and get your unit as full and expanded as possible. I typically will clamp down partially and then kegal up till I am fully expanded. Once fully expanded I tighten the clamp down till it prevents the kegeled blood from escaping back out. When you tighten the clamp it will expand your unit even further than what you are able to kegel it to.
If you have the thickness of the wrap and the final click of the clamp ideal, then you will be able to keep your unit super expanded for a full 10 minutes without your unit going real dark. For me that ideal is hard to hit.
There are different approaches. One is to not tighten is too tight, thus allowing your unit over the 10 minutes to lose some of the blood, allowing it to go a little softer but still in an expanded mode. This will create gains.
Another is to clamp so tight that there is no blood exchange and your unit will remain rock hard super expanded the full time. This approach will create a discolored dick by the end of 10 minutes (typically a few min. before the 10) and is the approach with the highest risk of long term penis discoloration. In my opinion the expansion feeling of this approach is what causes many of us to do it.
I believe you decrease the chance of discoloration by forcing fresh blood throughout your full unit after each clamping set.
You know you have had a good clamping session if your unit remains pretty plumped after you are done. If you over do a clamping session your unit will not stay as plump but tend to turtle up more - same type of response as other PE exercises. For me it is easy to overdo a clamping session because it feels so good while clamped.
For the last month I have even added clamped stretching which is an incredible feeling. You can wear your unit out pretty fast doing it so it is not something you want to be doing on a daily basis.
