I was considered "embarrassing" and that my companions did not wish to be associated with me because of this seems a bit emotionally charged, and I wouldn't consider it valuable feedback. If you have doubts you about your conduct, you can always ask someone else that was present for feedback, and it wouldn't hurt to gather similar feedback from past events.
And never bother responding. I understand that the moment was awkward and hurtful, but you'll need to toughen up a bit and deal with it: Smile, thank them for their feedback, ensure them you'll take it under consideration and walk away.
If you manage to keep smiling while you do all that, it'll confuse them even more ;)
