People really use dental dams? I mean, if someone is that dirty when even go there at all?
That's like saying "it's okay not to use a condom, it's a safe day today" when worrying about getting and std. it's not about cleanliness (not mainly anyway), it's about protection
When I say 'dirty' I'm talking about possible STI. With a little basic discretion I've never had anything worse than HPV. That said, I've never really been a part of modern "hookup" culture as it exists now, so maybe the rules have changed.
