Well welcome to the forum trystann and I do understand changing those perceptions of what would normally be acceptable and unacceptable with other people.
My wife and I have only truly been poly for a couple months. We did meet one couple nearby and we both had the same awkward moments they thought we were not interested in them. Unfortunately (for me) the male of the couple is interested in my wife and they are dating about once a month. I'm stuck with trying to find any woman even remotely open to the concept of polyamory without thinking I'm a cheating husband or common guy just looking to sleep around, lol.
It takes a strong relationship, almost no jealousy and alot of work to make it work even more than a normal mono relationship calls for. We thought we were very rock solid and stable in our marriage but still dealing with alot of bad feelings.
