As a single guy who earned a standing invitation to parties, this isn't something you can fool around with. I've never been with a group that demands all condoms all the time--my favorite group's new member orientation gives the condom talk, but also, "We're not the condom police." Condoms or bareback is up to the participants.
I don't think anybody actively likes condoms, but they're a fact of life. I certainly don't like them, but I'd never try and pull one of these stunts. It's obviously a bad thing to do, and I understand what a privilege I have by following the rules. I have had them come off, but there's always another one from the bowl.
Also, as I got to know people and got a track record, I found condoms becoming more and more optional, if I wanted. It's been a matter of knowing who people are, how responsible they are, and maintaining a reputation with them and the hosts. If that's in good shape, trusted partners have no issue going bareback with me. As I've formed relationships and been invited to more private groups, while not exactly an expectation, bareback is more than permitted. I love the flow of those weekends. :)
