Drafting and pack riding is one of the most enjoyable aspects of riding in my opinion. You can ride much faster with less energy spent if you aren't constantly breaking the wind by yourself.
Learning to ride at such close quarters takes some time and practice. At first, it can seem quite spooky and nerve wracking, but in time, it can become second nature. I suggest checking into any local recreational clubs and trying to get out more on some organized rides. Here, you can practice with like-minded people and learn the tips and protocol for proper pack riding. Good luck.
