Confused and Unsure

I think I might be Bi but growing up in a super religious household I didn’t have a way to experiment with it. I mentioned it to my sister once and she told me I was going to hell if I was Bi… I have had situations throughout life that have made me question. I went to a dance and ended up dancing very closely with a girl and I liked it. I went skinny dipping in a hot tub with a girl and we kissed. I am in a committed relationship now with a man but wish I could know what I feel like I missed out on? Am I crazy? 😂
