Which brings me to my next point!
No sleep means no sex
That's right. If you aren't getting enough sleep, your sex life will suffer dramatically. It's not just your cranky attitude that will put your partner off of doing the no-no-cha-cha -- a lack of sleep can also mess up your ability to, well, get it up.
"Poor sleep quantity and quality decreases our ability to recognize other people's emotions, decreases our ability to deal with stress, increases our anxiety, and decreases our sex drive," Dr. Oexman says.
If you're with a new partner who doesn't know how to sleep like a normal human being, instead always clinging to you like a malnourished baby koala, you need to have a conversation and right this ship immediately. Use the whole "sleep makes me better in bed" information as ammunition. Trust me, no one is willing to give up sex in favor of burrito-ing the blanket. And if they are, that person loves sleep more than your relationship; which points to a much bigger problem.
