Thanks for all the replies and advice - at least I know there are some (very) different underwear styles out there to try.

I think the issue is due to the combined size of my balls and also the amount of sack that I have, they can hang very low, especially when warm and they are above average in size. It is when I try to squeeze my cock, balls and the sack into a standard size brief that I start to have problems with the jock rash, it goes when I use the cream, but I'd rather not have to.

Anyway, I'm not complaining, still proud of them and spend as much time as possible commando so I don't have the problem.

Thanks again for your replies.

Andy
