I know that this is the obvious choice, but regular old Magnums are great. I too am particurlarly long. Although I'm significantly girthier than average, my thickness is not proportional to my length. So, normal condoms are too short and if I am going deep and "bottoming out" (lol) a woman, the entire condom enters, which isn't safe...it is important most of the length covered. Magnums are about 8" long, which is pretty damn good. The base is tapered though and fits snuggly. Like I said, I am thick but not fat enough to want a coke can circumference in a condom. Magnums aren't too broad to be practical for your friend.

The larg size condom "Maxx" is also good but hard to find. This condom is even snugger than a Magnum, and longer than average, but unfortunately not quite long enough for me.
