'Jewish' - 'Little man' - 'Wedding Vegetables' -- Norfolk Red you win todays award for the most NON-plain-speaking post. And - I'm told! - the women prefer the non-hooded as compared to the helmeted - (oops some more NON-plain speaking terminology.) And it's surprising how many posters 'have a friend' whose been circumcised (there I've said the 'C' word) but don't admit to having been done themselves!

Ok, ok I'm gonna help you out here... As someone who's had a couple of kids, I'll give you the benefit of my experience. Women are advised to sit on a rubber ring, so that nothing "catches" . So you probably need to make an "exclusion zone" of your own. Sticking with the aquatic devices, I'd suggest that you inflate a small armband and position that inside some comfortable fitting underwear. Maybe a couple of pairs of socks for added padding?
