I have to say that EEK is right, you slammed him pretty hard to do this.

I myself am an open bisexual, and am in a loving, monogamous relationship with a man.

Here is what you aren't realizing: It's the person inside that you're hurting. Man, woman, it doesn't matter. He loves you enough to want to be with you for the rest of his life, and he's openly made that commitment to you. You said yes to this commitment (I'm assuming as you're engaged), and then told him that he doesn't sexually fulfill you and you still want other partners. It's not the man you're hurting, but the person inside the shell who loves and adores you.

Aside from that, it's unfair. You're openly attracted to women and men, he's only attracted to women. If you're allowed to be with another partner which you're attracted to, he should be allowed the same. Until you're ready to share him, he shouldn't have to share you.

While I understand that it's hard to differentiate, your request is very selfish. He's not a toy to be kept on the back shelf and taken out when you want to play, he's a human being, and one who loves you very much. Don't destroy it because you want temporary passion.

Remember: Cheating is giving another person the attention and time that belongs to your partner, regardless of gender (unless previously specified for a distinct purpose).
