German Model

Policies vary regarding male models having an erection. Some instructors don't mind at all (especially with younger or inexperienced models), while others, including the Register Artists' Models (RAM) in the United Kingdom, consider this as cause for termination. In any case, it may be inconvenient for the artists, as the subject is not exactly the same as when the drawing session commenced.
