So, I (30F) am discovering myself as being fluid. I have been in heterosexual relationships, but do find some women and nonbinary people attractive.

I have only had one experience with a woman so far and it was in a threesome. She went down on me, and yes, it was probably the best head of my life.

Now, I am invited to another spicy party, but dominantely female. And I am nervous I am going to be expected to do things. Namely head. On top of that, these are friends. Not some randos. I am nervous about all of this and I feel like the least excited about the sex part than everyone else. I don't know if I want my first time going down to be in front of a group of people I know. I hope none of this comes off weird and people can tell me their thoughts. Am I overthinking all of this?
