We've all heard the age old adage, “Honesty is the best policy,” but do you really have to tell your spouse everything? It's actually perfectly okay to keep some secrets from your spouse, and might even be better for your relationship if you do. Here are a few examples of things you may not want to tell your spouse—and also don't need to.

That he's not all that great in bed

If you've had a few close personal relationships before settling on the person you married, it's natural to compare how they do in bed. If you've had better sex before, or perhaps the sex has gone a little stale, it's better to keep it to yourself.

 The good news is sex is something you can improve on. You can offer your significant other gentle coaching, without having to mention his current skills.

How much your fabulous new purse cost

Everyone has specific things they want, and sometimes those things are expensive. You shouldn't have to justify to your spouse why you want a fitbit or a fancy new dress, anymore than he should have to justify to you why he wants a new car part or a pair of basketball shoes.

You can once again make things go a little more smoothly by agreeing on a budget of discretionary income for you and your spouse. As long as it is within the budgeted amount, you can get what ever you want and the other can't complain.

That you did something silly

Sometimes we can do some pretty embarrassing things, like searching for your phone while talking on it, or having to go back to the house for a forgotten item. If something happened at work or while your spouse is away that truly embarrasses you, you don't have to share it with them.

Your friend's deepest secrets

Did your friend disclose a secret to you, and ask you to tell no one? When they say no one, they usually mean no one, including your significant other. Even if you normally have no problems sharing everything with your other half, think twice before sharing someone else's personal information. If you never keep even the slightest thing from your spouse, be sure to let your friends know that before they entrust you with sensitive information.

 How much you dislike their family

Everyone seems to have that one in-law who is an absolute nightmare. If you're not wild about his family, it's probably best not to say as much, especially if they're very close. If you do need to address some serious issues, such as outright abuses, you don't need to mention it if you merely dislike them.

Living with someone long term is a genuine commitment, and honest is generally the best policy. While you should definitely tell the truth about most things, it's okay to show a little discretion about some of the more sensitive things in life.
