This is working for me

You can move the 3D model to see it from different angles. Take a look at this link image:

I focus on the areas identified as: glans, corpus cavernosus urethra and bulb.

Penis base is covered by the Bulbospongeous muscle and it is a good muscle to work with. It causes contractions for ejaculation purposes.
Once I watched video of a surgeon, who partially cuts the Bulbospongeous muscle for premature ejaculation and reported 97% success rate.

Some guys use tight cockrings at the base of the penis for stamina purposes.
For edging, I tie the base of the penis with a 1 inch wide ruber band. Then I can use heavy stimulation and strong kegels. It makes the edging session great. And kegels can easily prevent ejaculation.

Another guy reported great stamina with clamped edging. You can read it here.

CAUTION
Those doing this type of training need significant condition or there is serious injury risk.

I forgot to mention it, I was going to mention it later but now that you bring that information I will mention it now. When I do what I called "masturbation kegels" I use one hand to masturbate and with the other I hold the base with a strong grip (I do an "ok sign" and grip the base tightly). With each kegel the penis is really engorged with blood and PONR is reached faster. I do that because I try to do everything as challenging as possible.
I am not familiarized with the term clamped edging but from your description I think is something similar. I am right? You are doing basically the same but instead of your hand you use a rubber band. (Sorry if I misunderstood the information. If that is not it tell us any correction you think must be done)

Injury to the penis or muscles?

Yes, you are doing the same thing but with hand. Rubber band or clamp makes things easy and fun.

Clamping video is here.

Glad to see your progress.

Both but the risk is more to the pelvic floor.

I had a pause in my sex life because my wife was on a medical treatment. I am back at it again. Last night we did it again but this time I failed to last 10 mins. Recently I bought a new supplement, one of those "everything but the sink" kind of supplement and I am sure that was the reason. It is basically a multivitamin with a lot of extra things. Since I began using it I felt the same as with other multivitamins, I feel that I am a loaded gun ready to shoot all day long. I have a theory on this. I think that there is a nutrient on those multivitamins that when it is in abundance in my body makes it easier to produce semen and makes it ready to shoot at any moment. You might be asking why I keep buying that kind of supplements if I know the effect it has on me, well is because I like natural bodybuilding and I notice a drop on energy when I don't use them. Being natural I need every energy source i can. I would love if someone reading this is currently using a multi (or any other thing that has many added vitamins) try to see if it has the same effect on you. Stop using it for 3 days and see if that makes it easier to control your ejaculation.

What vitamin is this? I'm an avid weight lifter myself and have found that carbs help regulate my energy levels more than anything else. In our quest to control our orgasms it is best to avoid adding in multiple factors at once so that you may identify what does and does not work. In this case was it the multivitamin or the fact that you were coming back from a sex hiatus? Just some food for thought.

What vitamin is this?

I believe it is made at a local company, probably it is not available at stores in your area. I will PM you a link so you can see the nutrition facts. I chose it just because it has a high astaxanthin dosage and it was a better deal to buy it than a bottle of plain astaxanthin (astaxanthin is a little bit pricey in my country).
