You shouldn't do any porn if it conflicts with your current job or any other jobs you might see yourself doing in years to come. So, if you work in an office environment, or in a hospital, school, etc, then keep well away from performing. On the other hand if you're a builder, a gardener, a plumber, etc, then by all means shag for queen and country and make us all proud.
Also, you might like to consider what your future kids will think of their old man pumping pussy for a living.
