Is it a sort of injury from clamping?

Attached pics are taken at 10th and 15th minutes of a clamping set.

After ~8 minutes of clamping the upper rim/shoulder of the glans starts to show light yellow and the yellow texture increases there after. I guess you can clearly see it in the pic.

Have I injured my glans by clamping?
I normally clamp for ~12 minutes. Once I remove the clamp the glans looks ok but with two light dark+purple dots over the two inner regions I have marked in the pics and those two are the regions from where it starts to get light yellowish from ~8 minutes onwards.
I think something is wrong with the glans. Fortunately, there is no problem with erectile function and absolutely no pain and the sensitivity is normal.
Appreciate your comments on this matter.

No one to comment?

Post a link to this thread in a couple of the clamping threads in the Main Forum kbvk. That might get some of the clamping vets to comment.

Maybe it’s my monitor but I can’t really see the yellowish color. I know that bruising skin can become yellow but I’m not positive if that would be the same for the glans. You say it hasn’t affected function so that is a good sign. At minimum I would hold off clamping for a little bit.

How long does it stick around?

That’s better. Thanks.

I guess it could be your monitor configurations. I cut down the set to 5 to 7 minutes. It looks better now.

It disappears immediately after removing the clamp. However there are two spots which look very small and light black+purple colored spots. Those are the two spots from which it starts/spreads to yellowish gradually after ~8 minutes of clamping. After about 12 minutes, the whole region I have marked shows up yellowish with more concentration on these two spots. I don’t clamp for more than 15 minutes in a set. I think it would get worsened if I go longer than 15 minutes. I have cut down to 5-7 minute set without this problem. I’ll continue with this short sets and see how it goes.
