Studies show lack of sleep and lack of sex drive go hand in hand. Sleep deprivation or lack of sleep can really put a damper on sexual activity or even wanting to have sex altogether. Lack of sleep in men and women causes testosterone levels to drop which is the sex drive hormone. This can lead to a lot of other issues not just sex drive. We should be getting at least 7 hours of sleep a night and for some people up to 10 for our bodies and libidos to be at maximum strength. So don’t skimp on the sleep, if you want to be a great lover for your fling you better have one hell of a sex drive to back it up. So get some sleep and get some sex.
