In most situations as far as relationships go, you find that you are completely satisfied in your relationship, but for some reason you find yourself curious for that same sex situation.
I am a married woman with three wonderful boys. I have a husband that one day noticed that something wasn't completely right about me. That I had this desire for woman. He loves me so much that he actually approached me and said "for you, I want happiness so go out there and see what it is that you are curious about". I am not interested in having threesomes with my husband and I, but I am interested in obtaining a friendship with a woman whom would like to experiment with me.
I respect all those in their lifestyles, I believe as long as you and your partner come to terms on what is appropriate for your relationship and you respect, honor and obey by those rules set fourth, then why not live your life to its fullest, there is only one life that you live.
