I hope that this does not sound like a dumb question. Yesterday, I did some laundry and mixed mine with a female friend of mine. After our stuff had already been washed together, I had noticed some blood on her underwear, and was hoping that if she should have AIDS that it did not get on my underwear or possibly be harmful to me. I thought that since my underwear goes around my penis that it doesn't stand a chance of infecting me.
