Energy Underground is a group of quality like-minded people that are interested in building a community for a sex-positive/swinger lifestyle in the energy producing states of North Dakota, Montana, Wyoming and South Dakota. We are consenting adults over the age of 25. Our group is open to couples, single females, and select single males. We are a drug and sexually transmitted infection/disease free group, by joining you agree that you are DDF. We are an OFF PREMISE Club (no spaces provided for intercourse at the event). We are a respectful of all that are in our group and expect that all members behave with respect and honor, we do not tolerate shaming. We do not promote or tolerate cheating, this behavior puts the membership, the group, and the lifestyle at risk. Our two most sacred values are that NO MEANS NO, and DISCRETION IS PARAMOUNT.
