Why would a female friend get mad when I talk about men?

[Anonymous]

I have a female friend and she has a boyfriend. We are both bisexual. I told her I never had a female friends with benefits but I’m open to it. She said she’s interested but I told her she’s in a relationship and don’t want to mess with someone that’s already taken. She said she’s fine with that. I proceed to talk to her about my male fwbs then she gets mad and ask why I’m messing with men but not girls. I said I haven’t found a girl yet. Anytime I bring up a guy she’s starts getting grumpy or quiet. Why would she get upset if she has a boyfriend?

She only get upset when I talk about men not women. She has other females she can mess around with so it don’t make sense why she would get upset over me sleeping with men

She might be jealous, who knows. I would talk to her about it though.

That’s a horrible lifestyle why would you cheat on your boyfriends

Maybe she's polyamorous or perhaps she's jealous.

She wants sex with both men and women
