Just in case it's of any use, here's my experience with different condoms along with a recent pic. I'm 7.5" non bone-pressed (8" BP) x 5.625" max girth.
- Trojan Ultra Thin (53 mm): A little small but quite stretchy, so it's doable
- Trojan Magnum (55 mm base, 62 mm tip): These fit really well - not tight at the tip, sufficiently snug at the base, mostly covers my length
- Trojan Magnum XL (58 mm base, 63 mm tip): This fit well too, although they're not any longer than the regular Magnum and the extra material makes it feel thicker. Not tight at the base, which is nice.
- Lifestyles Skyn large (56 mm): These are the only ones I've tried that very easily cover my entire length. A bit snugger than Magnums at the tip, but still comfortable. I like the thin non-latex material.
- Lifestyles Skyn regular (53 mm - in the pic below): Too short and too tight for my liking, enough that it makes it harder to maintain an erection.
