What I can say is this; focus on getting in good shape, improving your sense of humor, dress sense, and overall appearance. These things will improve your overall confidence so you will be more comfortable talking to girls. Also, these will make you more attractive. Then, the rest is really just a mixture of luck and patience. I'm 18 and haven't even had a kiss, done anything crazy at a party/club, etcetera. Don't let it affect your happiness if you find yourself without a girlfriend, trust me, it's not as brilliant as it seems. All of my mates have girlfriends who have mood swings, need attention all the time, or just emotionally manipulate them. I understand that you may feel as though you're missing out on something, as I did, but don't fall into the trap of, 'looking' for a girlfriend. You cannot force the process. Find things that make you happy, do the things I said above, and get good grades at school. When a girl comes along, you will know it's the right time. This is my experience.
