Definitely have no issues using them nor am I grossed out by them in any way. My body just gets all jacked up when I'm out of town and I'm basically constipated for 24-48 hrs. Not a conscious decision in any way. From what I understand, this happens to lots of people. I wonder if it's some sort of animal/territory instinct related thing This is only quasi-related but I read recently that when you sleep in a new place for the first time, your the left side of your brain remains partially alert to remain guarded. That's why a lot of people don't get quality sleep in a hotel, or at least the first night. That's interesting. My friend is like that. I can pretty much crash anywhere, especially big comfy hotel beds.
