People don't want to come off too strong or overly aggressive
no dude wants to be accused of being a creep or thirsty or whatever
Sure. And I can't speak to app dating, but even in 30 minutes or 15 minutes, meeting me, no one is going to think I am thirsty or a creep, or whatever. so just don't lead with your fears. texts always sound funny in public, because they are meant to be private, but people often are being very performative about it.
don't be generic and don't be too restrained. this is from memory first text from awhile ago, some super bad girl, Bay Area, very educated:
"Hey Marisa, this is --------, really had fun with you last night, loved talking about Aaliyah, lol- let's get sushi this week in Little Italy, if you are free"
I sent one after meeting someone out of town, like "Back home but I'm still thinking about you" that was it.
and yeah you can craft some romantic/sensual, well written text and just no response, and that is probably not even about the text.
