im Bi but how do I meet someone

Hi ladies im Bi and have a bf of 2 yrs we have a 7 month old bub and I'd really love to have a gf or three way. But I don't know how to meet someone. I feel really confused, I want to talk to a girl and get to know her not just get some action I want to see if im attracted to her first. Like dating. I've only ever hooked up with girls for some fun. And I really like the idea of having a three way.  I no lots of people use kik but there's so many fake accounts on there. Help me out please ladies!
