I'm a 37 year old; bi-curious white male and my mate is a beautiful 33 year old white female who knows of my bent and that I am serious when I say that I'd like to have my first bisexual encounter...but she doesn't know that I am actively looking for that person that might be the right fit in our relationship.
About you
Ideally; we'd always thought that a reasonably attractive person that would be exclusive to us as we would be to them. We have always realized that such a person would eventually go their own way; and can understand that; but in that time in which we'd share; we'd expect that they'd be exclusive to us and us to them.
