Give him a break: The same stressors that lower your libido affect his, too. Exhibit A: Researchers surveyed people three months after they had a child and found that fatigue, stress, and a lack of time were the most common reasons both men and women had low sexual desire. The findings were published in The Journal of Sexual Medicine.  While this research looked at post-partum sexuality specifically, “our research does counter the perception that men are ready and wanting all the time,” says Sari van Anders, PhD, assistant professor of psychology and women’s studies at the University of Michigan, and author of the study.  We certainly don’t need to tell that to the 16% of men who said they only want sex once a month (or less!) in a recent survey conducted by Sexology Australia. What’s more, almost of half of the men who experienced a decline in their sex drive cited stress as the cause.   “Stress is one of the biggest libido killers there is, and our modern lifestyle is to blame,” says Jay Cataldo, dating coach and author of Get Your Girlfriend Back. Think about it: “You think you’re going up to bed, and the next thing you know, you’re distracted on your iPad, and suddenly not in the mood,” says Patty Ann Tublin, PhD, a relationship expert and author of Not Tonight, Dear. I’ve Got A Business To Run. The same goes for your partner. If this describes you or your partner, log off! “Don’t check your Blackberry before you crawl into bed,” says Tublin. “It’s an instant mood-killer.” More from Prevention: What Kinky Sex Says About You  Relationship In A Rut?  Have Sex, Look Younger
