I wear my wedding band and I wear the ring Lind and I got for each other as well. Both on the ring fingers of each hand. But, I am not looking for another person right now. I guess, if I had a date I would go with the rings, just because I would have to tell the person sooner or later that this is what is my deal (if I haven't done so right from the start, which would be unlikely).
Both rings don't look like the normal golden ones, they are made of premium steel (hope that is the correct term) and I have two of them. Don't know if one would assume that those are couple rings or something like that.
If you feel that the ring is just a hindrance, leave it at home. It's just a symbol, you don't need it to validate your relationship with your husband, don't you? Just talk about what you are up to if you happen to meet a nice person.
Facts: 30, female, bi, v-type relationship with Sward (husband, straight, mono) and Lin (boyfriend, straight, mono), poly-fi and co-primary.
