Texting after cold approach number close and re-engaging

I opened her on Saturday afternoon on street. It was direct, strong eye contact and very slow pace. She reacted very well. Interaction was around 5 minutes. She was on her way to meet her friends for dinner. She told me to take her number. At one point, she sounds like saying 'I will eat my friends', which I teased 'I am not sure if I want to hang out with you'. She playfully responded 'Are you sure you don't want to be eaten?' in a fun way. I said 'Hmm, a second thought, maybe I should'. And we talked other stuff like where her family's original country etc.

On Tuesday evening, I texted here. She responded instantly. Although, there is no reply to my second text. My questions:

1. I remember Alex was mentioning that he wouldn't text too sexual for cold approach numbers. Is my response more sexual than it supposed to be?
2. I will re-engage. Though not sure, what would be the best way?

I appreciate all the feedback, thanks in advance!
