Single for a month now, started day gaming hard. I was out skating, isolated a girl who was also skating from her crew, and finally got her number. She had displayed IOIs in two previous conversations.

I talked to her a bit, got her number, and played around outside. I want to start verbally sexualizing in my initial text:

"You made those cutoffs look nice today."

I've read up on some text game and have had success in the past, but I feel a little self-conscious after being in an LTR for awhile (less practice) and not being too interested in cell phone usage.

I wouldn't compliment a girls looks like this on first approach, but I think it seems appropriate to invite flattery and explicit sexuality once. I'm also aware that I am single and possibly coming off as too desperate and/or aggressive to be attractive.

I've read up on the text game material, but still a little iffy and looking for advice here.

TL;DR - Should I include sexual flattery and escalation in my very first text to a girl that I have said maybe 500 words to over three encounters?

Also: Is it standard issue to exchange snapchat/instragram w/e the fuck early on? I'm in my late twenties, but mostly dating girls who are under or around 20.
