31 [M4A] England. Women that like bi men. Do they exist?

I am a bicurious guy. Always been straight but I want to explore my sexuality and have fun with everyone. I hear stories or see things online of mmf and women that love seeing their man with another man. But are women like that really out there? I would love nothing more than to be with a woman that loved that. She would help me explore and be supportive. Is it just a fantasy? Or can it be reality? Dm me if you would like to chat about it
