I think it's a case by case basis. Met a girl off of Tinder a couple weeks ago and we've been chatting. We plan to meet up tonight and she straight asked me if it's cool she don't give her number to me yet. I was like

because
a) I didn't ask for her number

. I'm already text messaging her at a solid rate...don't need a number for that. If we click on the first date, then I'll see what's up. I don't like a lot of women I've met off of dating apps having my number at first because
b) if the first date goes south and I'm not feeling her, I don't have to worry about her still trying to hit me up lol. Wish I did that with the girl that I went to the movies with last week
Again, it's a case by case basis, IMO
