Question for all / debate

Mods if this is tagged incorrectly just let me know what the right tag is so I can change it rather than fucking deleting the whole thread.

Basically this question is to people who are married or in very committed long term relationships, but mainly those who are married.

What do you think of the idea of feeling sexual attraction towards other people? Friends, coworkers, friends of your partner etc.

Once you start getting those thoughts is it a sign your marriage is in trouble? Does it mean you don’t really love your wife?

What if you start entertaining those thoughts? Like having sexy thoughts about the other person, fantasising, imagining sexy scenarios with them. Is that cheating?

At this this point does it mean your marriage is REALLY in trouble? Doesn’t it indicate that whatever your wife/husband does for you at home is not really enough?
