Well, I posted about this previously and there was not a single reply, but anyway:
Trojan gives away a free Magnum XL sample if you request it with their online form. I did this and it arrived in the mail a couple weeks later. I tried it on. I am approx. 8.25BPx5.38G. I was plenty long enough. It was cool to unroll a Magnum XL and still have a little shaft left. As far as girth, I filled it and it was snug due to the snug bottom. However, there was a littel too much space right under the head,. And this is because I have a big head, if that makes any sense. I had a big head and then it tapers in to my shaft, but this condom is designed with extra space under the head for some reason. My guess is that I would do better with the regular Magnum. It really has a lot to do with girth more than anything as the Magnum XL still didnt exactly cover my whole length and I dont consider myself hugely long. Keep in mind a 8" condom length includes the resevoir tip, which I guess is at least a 1/4" or so.
