Friends?

I told my friends I was bi and I dated a girl just to try it and they started laughing and didn't believe me. When they finally did 2 out of the 3 were worried i would hit on them. And the other one stuck up for me and she's still my best friend today but feel like I can't be myself in front of the other two, we used to like jokingly sexually massage each other but I'm scared to now. Any ideas?
