My take is as follows. People that have been in the industry for some length of time tend to work with the same people over and over. As the working relationship grows (no pun intended... okay I do intend that pun), a measure of trust grows with it. That being said, there are a lot of new faces and let's be honest we just went through a complete shut-down of the business because of an AIDS scare. As to the difficulty of taking a condom off for a money shot, well a pro isn't going to have too much trouble and a good editor should make things go seemingly seamlessly.
