How long after a girl gives a guy her number is it acceptable to contact her?

[musicloverr8]

I am asking this is the sense of 'expiration'. After a girl gives a guy her number, he should follow up with her within a reasonable time frame. How long should a girl "wait" to hear from a guy?

within 24 hours.

2 days max

3 days max

within 1 week max

whenever

I picked 'B' because "within 2 days max" could mean anywhere from an hour to 48 hours later.

Doesn’t matter. Do what you like. Life is too short for all these bullshit rules. If you have a connection do what you do. That’s all that matters

I usually text them four days after asking for her number, then I make a date with her to have sex, after we have sex, I block her and never contact her again.

a week is customary as to not come off too thirsty to her.

A whole week? That's a long time to ignore
