I'm A Lesbian And My Girlfriend Is Bisexual. How Can I Tell If She Misses Men?

By the fact that she is staying with you. I am bi, and know that I would never leave a girlfriend I like enough to continue seeing.  Don't forget that any guy she has dated has to wonder if he will be left for a woman. Trust her actions: If she stays with you, she wants you, not a random person attached to a dick. Tell her if ever she wasn't satisfied to just tell you and you can both work on it and try something new as a couple.

You could just ask her. Communication is vital to any successful relationship.

The way she act to thats what I think

Thats a hard one to answer best way talk to her honesty is the best way

By the way she stares at them....body language dude...I know my ex did it to me to.

I can give you the easy answer, she will dump you!  I am tired of being right!
