I'm in a serious relationship but we are both free to see and date others. We aren't "swingers" but rather two people willing to let each other have meaningful relationships with people of the opposite --- even if that entails being physical.
We would like someday to have a close enough relationship with another female and make her part of the family. If that happens we think the love we already have would be enhanced. It would have to be someone who loves us both and realizes that relationships don't have to fit into the mold society dictates. (i.e. One man and one woman).
So if you would like to meet a nice guy

Take care.
