I went out to a club for the first time in my life last night.
I managed to get 4 phone numbers from HBs I was grinding with. One HB even asked me for my number first.
This other HB positioned my hands above the waistband of her pants while we were grinding and even allowed me to stick my finger in her.
I pointed to my cheek and told each of them to kiss me before we parted.

However, I feel as if there wasn't much comfort built because 3/4 HBs don't even know my name.

How do I arrange for these girls to meet me again?
Should I wait a few days before I call them?

I've never done something like this before.

Thanks guys.

I would send a flirty/funny message to 1 or 2 of them to see what happens/if they even remember you. For the rest, probably drop a txt next time you're going out and tell them they should come.
