The dripping... well, if it happens, it happens; it does not take anything from the work. The dripping just proves that you were not trying to control the work, but the work was developing by itself and if it drips, it's a natural part in the evolution of the work.
I've done sexual stuff before - onstage, which is even more emotionally difficult. With a TV crew around, you are stopping and starting; it becomes really technical. It's not erotic at all.
