I personally always give my number To me it seems more confident and Im more telling then asking.

If she texts me great, if she doesnt no loss.

I feel like it makes it easier and shows they have interest since they have to text first.

Also feel like most people ask for numbers so maybe it sets me apart from them?

Question being, what works better or maybe are there better ways to ask for a number that seems like more of a power move? To me giving my number seems more confident/power play but open to other options
