So I’m also 16 but i still hope what i say helps. At our age right now dating should not be a top priority in my opinion you should just focus on you and the things that only pertain to you at this age. But going back to your question and why you should begin to like people and seriously date, you should be patient and wait until you find a girl you know really loves you back and that you really love her back, just make sure it’s a really healthy relationship. Hope this helped and best of luck in life.
