My answer to you is what does it matter ? You stated you were not religious. so sin should not be a problem.  i think its foolish to obey any man made religious laws. Im not Religious myself evin though i was brought up a Roman Catholic .this is the 21 st century not 1 AD . Religious Dictatorship is Dead !! most of us are educated now & no longer sheep to be lead by foolish Mythology of the Past !   Use your common sense &  Logic
