I'm also a bisexual woman in a monogamous marriage with a man.

He knows about my past, and before we got married we decided that we would be open to talking about some sort of open relationship if I needed that later. I didn't know what it would be like to go without women, but I've been with only my husband for five years now.

I dated bisexual married women (with their husband's permission) before I met my husband, and that was pretty drama free. They had happy lives and good marriages. But I know my husband would really prefer to stay monogamous if we can, so we have stayed that way--at least for now.

I'm not suggesting that you should change your relationship, especially since you said you are a one-partner type of person. Just know that plenty of women are in our situation and if monogamy with a man isn't something you can commit to there are solutions besides doing something you regret.

Bridger has some good ideas about how you can incorporate that part of your desires into your sex life with your husband (and with yourself) while staying monogamous. I know it's not the same, but it helps, and...I don't know...for me it helps just to be able to bring that part of myself into the relationship. I don't want to leave that part of me behind, even if I've left women behind. (Don't know if that makes sense or is relevant to you.)

It sounds like you are feeling really tempted right now and that sucks. Go talk to your husband. Yep, it's scary, but you already said you know it's the right thing to do. You can do it.

Yay for you for being aware of your feelings before you acted. You have nothing to feel bad about--having desires and fantasizing is not wrong. Hugs!
