Seems strange but always seems to work better with the ones I wait for to call me first. They should call the next day. I think age and shoes sizes doesn't matter dat much. I would wait for the guy to make the first few moves and see whether things are moving on a steady momentum. A guy who doesn't do that is a waste of time, words and thoughts.
Life's too short to play games.
When something good comes along, grab it. If you had a really good time either should call to say something least you will both be waiting for the other to call. But,don't let a good thing slip away from you without a thought. You'll know by the feel of the conversation if it's worth pursuing. Well I think the guy should call the next day.
