I just remeasured and I got 5.5 around. It just doesn't seem that thick to me, but I guess I am. And the regular trojans fit me fine, so I don't think that they are made all that small. Although I didn't try the magnums, maybe the magnums would fit. I seriously didn't think this post would have turned into everyone attacking me for saying magnums were for thick guys. The name MAGNUM, is in the title. Lol. Sorry to make an assumption that obviously sent everyone going crazy.
You might have read that you were 0.5" away from 5", in the wrong direction!
I don't really know why so many people jumped all over the word "magnums," either. Regular condoms were made to stretch - same with magnums and magnums XLs, I would imagine. I haven't really used a condom in a while, but I once borrowed one from my stepbrother and it was a Magnum. I'm not sure if he bought it because of the name or because he actually needed it - I didn't care to find out, and even if I did, I would probably be banned if I posted about it.
Anyway, needless to say that the condom was useless for me. So, if a guy actually needed Magnums, I would be pretty impressed. But of course, that clearly doesn't apply to any one else on this site... Why am I not surprised?
