My contention is simple - when we're in Second Life to work, we can use the same techniques we use in first life to focus on the task at hand rather than that gorgeous avatar. If we want, later, to consensually jump that avatar's virtual bones (to be deliberately somewhat crude) and they are interested too, then just like flirting in the office, we can run off together and do this. However, if we're in a space that forbids this - Lively I'm remembering you here, but not only you - there is that allure of the forbidden, the censored, the naughty. People can, and will, work around the limitations in some quite amazingly inventive ways. Knowing it's not forbidden lets us (as a group) apply that energy and creativity to the task at hand when we're working, and apply it to the avatar at hand when we're not - in much the same way we learn how to do as adults.
