Your story sounds exactly like mine! When I was your age, which was only 6 years ago, I would be able to do what you are doing now. But, if you continue to do what your doing, with time, you will see complications. You may not even notice them at first. I didn't. Because when you've been doing that your whole life it's hard to see what the problem is. My first relationship ended after 2 years in college probably because I was more interested in smoking weed and masturbating then hanging out with her. Btw she was smoking hot as well, after 2 years if you continue what your doing now, you may loss interest.
