..... maybe can offer gloryhole-sex (BJ + FJ), makes it really safe as an alternative basic-sex offer.
Come on government, be creative and smart and do some testing and give the GL houses some financial support to build the boxes in their houses
Should be ok for a transition period of a few months. If it turns out to be safe the shops can offer more services later = more bucks in the pocket.
Cannot be soo difficult to re-open GL. Create a master plan with creative ideas and put it too action.... don't wait longer, other issues are growing bigger already on your backyard.
