What’s a healthy sex life? Is it true that what’s good for some might not work for others? According to sex therapist Ian Kerner, couples should be having sex once a week, minimum. Kerner’s seeing what he calls an “epidemic” of sexless relationships and believes that things like social and economic stresses, health problems and the rise of internet porn are to blame. Reconnecting with your partner on a physical level helps reaffirm intimacy and rebuild connections. But! He says, sex isn’t just about connecting with your partner in an intimate way. It’s also great for reducing stress, boosting immunity and releasing pleasure chemicals called endorphins. Some other added benefits: steady sex helps boost confidence and has been shown to make people more successful at work.
