I've read somewhere that you should only ask a girl out if she's being receptive - the invitation is then like a 'reward' for her good behavior.

It makes sense, you don't want to ask out unreceptive girls.

But how do you make her try harder, over text? Like 2 days ago I slept with a girl on a first date, and now I want to ask her out again. But how do I make her earn it? The only thing she's texted me so far is if we had used condoms (we were drunk). I don't know if asking her out after this is very smooth.

What do you think about this rule of asking her out being a reward?
