What are some effective ways to escalate with a girl on a date. This would be in the context of a first and second date. Assuming attraction is already there (she agreed to give you her number and go on a date with you), it should be about building comfort now right?

There is a lot of conflicting info on this out there. Compliment the girl, dont compliment the girl. Even if you think shes smoking hot your not suppose to say anything like that?

Any info or resources appreciated gents.
