The 6 biggest mistakes couples make in bed

Mistake #2: Forgoing sex because you’re not in the mood

Adult life is exhausting, and stress can decrease desire, says Nelson. But if you wait to have sex until you have plenty of free time, you may be waiting a long time.

The fix: Just do it, and you’ll probably be glad that you did. If you’re genuinely crazed from obligations and short on time, you can still fit in a quickie, says Nelson. “The sexual contact will make you feel connected to your partner and can reduce the stress in your marriage,” says Nelson. Sex also helps release endorphin and dopamine, serotonin, and other brain chemicals that can reduce your stress during the day and help you sleep better at night.
