It might suprise you, but most of us are bi-curious. You probably thought about having sexual and/or romantic relationship with someone or anyone of same sex, and so did your girlfriend. The usual signs might be her looking at the naked pictures or videos of other girls, and she also might be reading about relationship with other girls, thinking or talking about it. The best thing to do is to talk about it with her. You also need to know that if she really is bi-curious, it doesn't mean she wants monogamous relationship (relationship with multiple partners) or that she will cheat on you, and you need to understand if she really is bi-curious or bisexual, because if you criticize her for it, it might ruin your relationship.
Just ask her most girls are honest with it
Does the idea of having physical relations with both sexes appeal to you? If yes, then yes, you are. If no, then you, you're not.
No

Tell his girlfriend or tell him to dump her for you
Determining if someone is bicurious depends on their personal feelings and experiences regarding sexual attraction and identity. If Tom has expressed interest in exploring attraction to both genders or has shown curiosity about same-sex experiences, he might identify as bicurious. Ultimately, only Tom can accurately define his own sexual orientation and feelings.
Gay, straight, bisexual, lesbian, bicurious, experimental
