Alright, you need to get over this. I feel awkward about talking to my dad about girls too, but if you can reach into the world of dating, it isn't worth holding yourself back. What if someday you don't have as much luck with girls? What happens years down the road when you're 30 and haven't had any experience with girls at all.
I have the same problem, but if a girl asked me out, I would definitely accept. I wish I was in your position. Don't squander it.
Good luck
