I'm told that quite a lot of 'males' who end up in the ER are underdressed. It depends who says it but it's on average about 5% (their figures). Medical staff are not really bothered about your clothing, they've seen it all. If it gets in the way they'll cut the clothing off. But I do have to admit that my parents instilled a fear in me that I'd end up in the hospital someday in less than perfectly pristine underwear and they made me carry clean socks in my pockets just incase.

I'm just glad that you are okay.
