Who are You?
What to you believe actually makes up "You" your "Identity"
One way to look at it: Are you are a core bundle of unchangeable attributes?
Another way to look at it: Are you a sum of all of your experiences?
Depending on how you see yourself will determine your apporach
When you say the "pickup" type stuff isn't you, who are you? Everyone says to be yourself, but I sure as hell at the age of 16 didn't know who I was. I am 25 and I am just now really establishing my true identity, and who I fell best being.
I encourage you to try on many different suits, see what fits and appreciate and the ones you try that don't work. Acknowledge that they are not for you and simply move on to try on the next thing. The key is not to get too hung up on one idea or one identity.
I believe adolescence is the hardest time there is as a human. Being pulled so many different directions, your parents telling you one thing your friends telling you another.
As far as your desire for female attention, there is an interesting paradox at work in the realm of attracting the opposite sex. It seems the more you want/need that attention the more elusive it becomes. But those who seemingly don't want it are bombarded with it. You would be well served to research the mechanics of attraction, and what really triggers attraction.
It seems you have looked into the world of pickup a little bit, and while it can be a slimy and manipulative practice, there are some good honest people that truly want to better themselves and help others do the same.
