Do very good looking people do better on dates if they're slightly nervous than being too chill?

Do you often start to think that you don't excite them enough?

Yes

No difference

The calmer the better, no matter how good looking

Focus on the Present and person as all male or female knows fearfully nervous. That fear is sometimes why one seems chilled, smug, aloof, or don't care. Always nervous in personal interaction, whether it is 300 graduate program professors in conference or worse...1 little girl, is commonplace. Only the psychopath or sociopath does not, at some point in a date, get the "nervousness" or "chill out... chill... chill... chill self-talk or feeling.

When I was a teenager I was pretty but my rejection rate by guys who liked me was almost 100% cause I got anxiety around guys who wanted to date me. I know many guys in their 20s who struggle either with anxiety or uncontrolled jealousy and passion. It’s why marriage in the 30s is more common.

Good question. When it was good, it didn't make me nervous at all. When it did, it was because she had stuff to hide (e. g. crimes in her family, fake identity or previous fake immigration documents/forged documents etc), so she'd get very nervous that I am not a bozo nor a criminal/of a similar background but perfectly clear.
No matter how much attraction there might be, such girls cannot really be helped/cannot get a longer term date (since they refuse to be honest but keep insisting on a fake reality)
