Finding a girl🤪

Ok so the guy I'm dating is the first one that really accepted me for my sexuality of being bisexual. Wtbs this is also my first time being true with myself about it. I always have the urge to have sex with a female, but I want him to join as well. I know that may sound crazy but I can't have one without the other. I never did the girlfriend thing but if I do she have to be our gf. He have no problem with it! The hardest part for me is approaching a female to start a conversation..
