Questioning

So about a month ago my bestie and I were really drunk and I went down on her, but when she tried to go down on me, I freaked out and started crying. Since then I can’t stop thinking about what it wouldve been like. I tried to talk to her about it, but she says she doesn’t remember. She has a bf now, so I know it wont happen again, but I’m not jealous or anything. I guess im just trying to figure out what this means, i mean ive had crushes on so many guys, but only ever had a crush on one girl in hs.(not my bestie) Can anyone help?
