Is it normal that i'm a lesbian but i hate fingering?

Ok so this is probably weird but I know I'm a lesbian for sure. I've been dating this woman for a little over a year and I love her to death. We've been together sexually and I love to pleasure her but I just can't stand fingering her. I love scissoring and oral sex with her but if I finger her I feel like i want to get sick. I know it's not just her because I've tried it on my self and get the same reaction. So tell me, is this normal?
