Very good points Zelev about not wanting to end up like Guy #2.
I would say that dating now should be completely on your terms and when you feel comfy with whomever. There is nothing wrong with being up front and honest with all the guys you date that you are not ready for a committed relationship. If and when the time comes that you are interested in settling down a bit, you will know it and you can adjust your sights then.
Have some fun....have a blast. Enjoy your freedom and meeting new folks. Take good care of yourself!
