I spent my teens/early 20s with the messages about "enthusiastic consent" overinternalized, to such a degree that I would ask permission for every little thing (even holding hands or a kiss). I now understand that, like many things, this can't be measured without changing it, so now I focus more on body language and other cues, and my partners and me both seem much happier.

I also have strong social anxiety, so that plays into it.
