What do you know about “sex fasting”? As the name implies, “sex fasting” means going without ANY sexual activity…even the five-knuckle shuffle…for a specific amount of time, be it a week, a month, or longer. Advocates of the practice say it boosts libido, helps a guy last longer in bed, and might even “promote more intense orgasms.” As for reasons why someone might feel the need to try “sex fasting” in the first place, experts say it could be as simple as “looking for a physical or emotional reset,” to get a “fresh perspective” on your sexuality, or to allow you to “reevaluate potentially unhealthy sexual patterns.”
