If you often find yourself reminiscing about hot and heavy weekends spent in bed at the start of your relationship, you're not alone.
Once that can't-keep-your-hands-off-each-other period dies down, it's normal to draw a comparison between the initial stages of your romance and the steadier routine you've become accustomed to.
But if you're really tying yourself in knots over how often your reach the big O with your other half, then it might be worth taking the advice of experts who insist once a week is enough to boost contentment levels in any relationship.
According to a study led by researchers at the University of Toronto, more than once a week doesn't generally make a difference to how happy you feel with your partner (Although, that's not to say you shouldn't go at it as often as you both want, obvs.)
After analysing findings from a 23-year study which harnessed the experiences of 25,000 people, researchers established that once a week was average and enough to boost happiness levels.
Speaking to CNN,study leader Amy Muise said: "I do think couples can end up feeling pressure to try to engage in sex as frequently as possible."
Hear that ladies? Once a week and you'll be laughing.
