Lots of places are closing. Any good places to meet and have "open" fun in S.E. Wisconsin?
Have you tried the Bath houses in MKE or Kenosha area? Also there is a group that meets a couple times a month in Madison at a house getting 10-25 guys at a time. From North Central part of state myself so do not know area well. Check out post at bottom of first page about CampNCN, it has an All Male event this weekend that will be wild, wish I could be there but prior commitments.
There is also a group called WNM (Wisconsin Nude Men). They're headquartered in Saukville and have monthly events there and in other locations. It's a great group, but don't be fooled. Despite the name, WNM is not a nudist group. It's primarily about open minded guys who meet for casual sex or to watch others do the same. https://www.wnmclub.com/general-information.html
