Glory Holes

I know that these are some, well, holes in the walls of saunas, bathrooms, etc. where you fit your dick and someone (it can be either a man or a woman) is sucking it anonymously. Of course, these are not regular saunas, bathrooms, but they are placed in swingers, gay and adult bars.
How many bars with glory holes do you know and where are they located?
I find these truly exciting and it's on my bucket list for 2019 (I am the female half). My husband would looove to watch it.

I've never been to a glory hole cuz I don't trust if there's going to be a woman on the other side or not. But you're more than welcome to suck my cock and have your husband watch

I want to do whatever

I’d love to do this with you. Sounds like fun Here is my cell 7*****3. Let’s make it happen
