Husband and me have strickt rules about that.
No friends, no coworkers.
Strangers that I pick up when I goes fishing, I always get approached, I talks to them, get to know them and evaluate them, informing husband if he is not with me, then he and I chat, and we both have to agree, if we dont feel sure, we drop the bull, and I go fishing for some other.
Alternative we have used Craighslist to fish, chatting with them, and that way got to know them as well as posible.
There is some exitment in playing the "getting picked up" game as well as the slutwife game.
If I go with them, my GPS is always on, husband follows me, and listen in on our conversations. New trick he has started, is sending pictures of the building I am in, if its the right, I show to bull, who sometimes then ask me if husband is outside.
This of cause the times where husband cannot be with me, we prefere he sit and watch.
Its also a rule, never same bull twice, I have to often experianced that bulls found this way, did not understand when i explain that its a game husband and I play, that i love my husband and will not leave him. One time only, should reduce the occureanses of "Falling in love" bulls.
Acturaly its a problem, even though I try to specify the game before going with a bull.
On my weekend in Istanbull, I had a extention to husbands hand, we had found a guy, that I could call and come go with me. Primaraly for getting good photo, but also as a security, perfect as husband was not with me.
