what's important on the first date ?

Respect, being polite and being yourself

NOT to feel like you're going in for a job interview.

Try not to vomit at dinner

Spending a lot of money.

Food.

Closing the gap. Becoming comfortable with each other. Light touching, laughing, eye contact. Also sex.

Good chemistry and an openness and willingness to get to know each other

I agree, respect is a must...but chemistry is good also :)

Just be yourself, and let them do the same...

showing up

Sex

Absolutely
