Ok guys
I don't know if yours answers helped me or not. I guess with a girth of 6.4, you'd use a wider brand. Anyway, if you come to Switzerland, try the regular CREST and let me know if it 's fine or not. Maybe I might like being tight. I actually never used extra large ones and it's fine. I only remember being very uncomfortable with some French condoms. I had no room, it endend up broken, and since then, my girlfriend wants me to keep on the same brand.

So still with regular condoms, but still happy to have a rather large one (much more fun when I hold it)
