Bisexuality Support Group
Bisexuality is a sexual orientation which refers to the aesthetic, romantic, and/or sexual attraction of individuals to other individuals of both their own and the opposite gender or sex. Most bisexuals are not equally attracted to men and women, and may even shift between states of finding either sex exclusively attractive over the course of time.

But, my unchecked urges usually bring nothing but trouble. Be careful!
I love my straight male partner very much but lately feel a very strong desire to be with other women. I don't want to hurt him, but I also feel a need to tell him the truth about how I'm feeling. I am seriously conflicted just like you.
I'm not sure if I'm in a position to give you advice, because I haven't resolved this issue. However, for myself, I feel that if these feelings are so overwhelming that they consume me, I should tell him how I'm feeling and ask if he's ok with me dating women temporarily (open relationship). I think it's important to be open and honest with your partner and to always let them know you love them.
What do you guys think of this advice?? I'm hoping it helps you, cart86. Let us know how it goes.
