As long as your teeth are well kept it should be fine. Sometimes the position of growth for each tooth crown is genetically determined and there's nothing you can do about it, therefore, beyond your control, hence why people have braces w/e.
I don't believe it's a significant matter in terms of dating. There are much more important characteristics that I require from a guy inorder to date him ie. honestly, compassionate, caring etc, these are some qualities that would over-ride any physical deficiency.
