Finding glory holes seems to be easy enough if you have a xxx adult bookstore near you or adult theater though not all of them have them. Plenty of info on the internet about where to do, find them, and how management feels about sex activity on the premises. And, whether the police regularly patrol. Had many experiences over the years. Safe sex is encouraged. You can also find them and plenty of other stuff at gay bath houses. Again, most of the info about locations, types of people you'll find, cleanliness, staff friendliness, etc. readily available. Of course, you can also find the random glory hole in rest areas, college or university libraries or buildings, etc. Be careful out there! Good luck.
