what two consenting adults agree to is fine, if they enjoy meaningless sex all the power to them

But realistically you dont know each other, the attraction may be strong but so what?

You dont really know each other.

If you are the type of person that values sex , intimacy and long term committed relationship having sex on the first date isn't your thing.

Because you believe that intimacy is best enjoy after a bond is established.

I personally dont value someone a potential long term partner If she is willing to have sex on the first date or two especially if we were out and drinks were involved.

I would have serious trust issues with her if she is out with friends whether its a girls weekend or vacation somewhere, and she meets a charming guy that has the gift of the gab.

On the other hand if that is what two people want I say go for it and God bless you.
