How long do guys wait to call?

Call right away...

Just depends, but I usually wait 2 to 3 days.

If the is guy interested in you, he'll call. He'll hold onto your number for dear life and even though he might follow the ridiculous 3-day waiting period, your phone will ring and it will be him asking you out.

If you know he is a player than you are going into it eyes wide open. It's when they play you along and then you find out that they are just players that you can hate them.
