That’s why decided to put together a sexy guide for those fighting against one of the most common symptoms of aging: back pain. Back pain strikes all of us at some point. But just because you can’t entertain all the acrobatics in bed you used to enjoy doesn’t mean you can’t have great sex, still. Check out our list of suggested sex positions below. Doggy Style In 2014, a group of researchers from the University of Waterloo in Canada asked a group of couples to have sex in five different positions, you know, for science. With the help of infrared and electromagnetic motion capture systems, they were able to identify which positions best catered to those suffering from bad backs. Doggy style, as it turns out, came out on top. Having your partner support her weight with her hands is one way to make sure you can stay in a more neutral position during sex. Having her support her weight with her elbows is an even more effective approach. The scientists refer to it as a “spine conserving” position, meaning it requires the least of motion out of you. Modified Missionary This position requires you get on top and support your weight with your hands. Instead of elevating her legs, your partner should lower them flat out on the bed. The position doesn’t require a lot of arching or thrusting, which makes things easier on the spine. Another potential variation of this position, albeit slightly less effective at preventing back pain, would be one in which you lower yourself down to your elbows while your partner flexes her hips and knees slightly upward. This is going to gives her more control, so you don’t have to drive the motion all on your own. The less you’re moving around, the more your spine will thank you for it. Spooning Though this one isn’t exactly easy on the spine, the very nature of the position caters to those who experience pain when arching their back. It also allows you to control the pace, which means you can move in whatever way that is most comfortable for you. Another added perk involves the fact that this position does not cater to quick thrusts, which gives you a better shot at lasting longer in bed. It also that frees up your hands, giving you the opportunity to explore other erogenous areas on your partner.
