DLD, the whole bundle issue is super. Flaccid or erect, I believe you get stretch from bundles. You have to, because you are pulling against yourself. When you twist, you are stetching itself. I am constantly talking about the "wire" or something similiar down the shaft. I am told it is the tunica, but recently in a post with BIB we talked about it being the septum of the tunica. This septum is a very tough fibrous bundle of something. If we can break down this septum, then we can stetch the tunica. The tunica itself, the "tube" is easy to stetch, I think, but we can't because that tunica which is the top of the tunica, as I understand, won't give. So, how, do we stretch this tunica?
I think that bundled stetches both flaccid and erect are awesome. Yes, they should be done when we are in good shape. They are intense. But you posted recently that the Penis is a very, very versitile and adaptive organ. Yes, it is and we can really give it a lot of work. I do think it is more that we need to know what to do and do right than a danger of hurting it. I have been at this for many years and I don't think there is too much that I can do to my schlong that would surprise it. I often get discoloration but seldom bruise. The blood spots on the glans that appear when we really apply presure, go away in a day or two. Same is true when we really put pressure on the schlong in bundles, you will get discoloration that will disappear in a day or two.
I am wanting answers to stretching that "wire" septum that is part of the tunica. GS
