I can't watch porn while in class. My professor can't (or hopefully can't) show us porn on the projector. Why should government officials literally jerk off instead of do their job? Wait till after work. However, the only exception should be the president. Poor guy is on call 24/7 for up to 8 years. His testicles (assuming we're talking about Obama) might explode if he couldn't watch porn for 8 years.
