As a man of considerable wealth and influence,Lex
would have personal body guards and other security
for himself and family. Nothing uncommon there. It would be unusual not to. The distruction of the
Daily Planet was an industrial accident. They happen.Lois must have been comfortable enough with Lex to marry him and give herself over to their marrage bed.She admits , sex with him was "nice".
Although her unhappyness is profund, it is Clark's arrival that gives it focus and a name. She may not be cheating physically, but emotionally. Of course, if Lex is a rat, then all bets are off.
