It depends on many things,If your camming with one another and the people are naked yes in a way its cheating but only if the husband or wife dosnt know what your doing online, if your sneeking around hiding from your partner or staying up late after they go to bed its a form of cheating also.I think if all partys know, you will never get caught up in lies,Just cos you cant touch them,dosnt mean its not real,Hearts become involved and anyone that says they dont is lieing.But still if your not meeting them its not that bad,again as long as your partner knows,whats the use of hiding what you like.
