Well, one date seems a bit early to be exclusive, or so I would think.
I assume you're being honest with each girl, that they are aware, as they should be using a dating site, that you are also meeting other women?
Some have different opinions, but to me, the first dates are to establish whether both parties want to take it further. On first , second, etc, dates both parties are trying to impress - it's the later ones when the true self comes out.
