No, I'm not sure, because I've never used them. When I first realized that regular condoms were too small for me I bought Magnums. But even they seemed too difficult to put on. It wasn't until after reading around here that I discovered there is a larger condom called Magnum XL. So I'd like to get those and see if they are better for me.
Well, I can tell you that I tried the large-condom assortment from Condomania.com, and all but three of the twelve condoms in the package were too tight for me to wear with comfort, and my dick is only (I only add the "only" because of the comparison with you!) 6½" around toward the base. (People talk about how far condoms will stretch, but the elasticity of the tube doesn't do you any good if the ring at the base is digging into the base of your dick so far that it's making it numb!) The three were: Trojan Magnum, Trojan Magnum XL, and Helmet XL, which I think was about as wide as the Magnum regular, which, of course, is not as wide as the XL. So I really doubt that there is any condom wider than the Magnum XL. There used to be a brand called They Fit which made condoms in a wide variety of sizes, but the last that I heard, they were closed down because they failed some test of product integrity (which is pretty damned important where condoms are concerned!). Anyway, get some Magnum XL's and hope that they are comfortable for you.
