Coming out?

So I learned that I was bi when I was like 12 years old. I am now 21. I didn't tell anyone until I was like 17. I told my boyfriend (which has been since I was 15) and I told my cousin while we were drunk lol my boyfriend is totally fine with me being into girls, but I've never been with a girl yet. I've kissed a few of my friends, I always saw it as a best friend kiss, but once, my best friend started coming on too strong. She always wanted to come see me, always tried taking me away from my boyfriend. I didn't like it because, well, I had a boyfriend and I didn't want to disrespect him like that. I'm not sure is she's gay, and I don't think she knows I am. But at this point in my life I assumed everybody knew, because I would drop hints here and there but my other friend made me realize that only 2 people in my life know about it. I'm not sure how to come out, or if I even should because I have a boyfriend. Andddd I am a very awkward person. I HATE HATE HATE talking about deep, personal shit with people other than my boyfriend. It's all good online but I cannot do it in person. Can someone help me with some tips on coming out? It'd be greatly appreciated ❤️💛💚💙💜
