Actually, now that I think about it, since you have such a huge girth but questioning it, you may not have realized just how thick you really are. You probably are using magnums or magnumxls. They aren't thick enough for you. You may want to get some custom condoms. Try putting in your stats here:

You remind me of myself in questioning if your dick is actually big or not. I still doubt myself, don't think its that big... but your dick is absolutely massively thick! Length is seemingly average to slightly above average but that huge girth just might be throwing off my perception it really is that thick!
