Can you get stds by wearing someone else's pants?

All answers refer to unlaundered pants worn by someone w/an STD. Crab, definitely. They can cling to the fabric and then attach to your pubic hair once you put the pants on. Other STD's I would say it would be very, very difficult and the chances are quite slim. Bacteria and viruses don't survive for long in environment that aren't optimal for incubating them. A pair of pants that had been worn by someone w/an STD, even one as potent as HIV, and laid around for a while before being put on by another person is not a good breeding ground for an STD. I suppose technically if someone had gotten a reasonable amount of urinate, feces, semen, or vaginal fluid inside the pants and the second wearer put them on while the substance was still "fresh", then there would be a chance of contracting something. However, who wouldn't notice the odor or wetness and continue to don them? If the "samples" had been dormant for quite some time, I would think one would have to not wear underwear and really squirm around alot to contract something due to the fact that most of the bacteria or viruses contained in the fluids would not have survived by that time. As you can tell, this answer was quite thorough, taking into consideration all possible scenarios. (By the way, I am a registered nurse.)
