Since you are still legally under age you need to progress slowly so no laws are broken anywhere. This in particular is why I am not advising that you pack up and move to the big city. However, moving to a large city is a helpful method to get yourself a gentleman if that is what you are looking for. In the meantime however look on the internet for gay centers and the whathave you. Try this one if you can (I hope this linkage thing works)
gay and lesbian and transgender centers
Anyway the thing is you are still quite young so don't just throw yourself into any relationship tat comes along. Take the same approach as the heterosexual world does, get to know the person and see how things go. Once you find the right partner life gets a little easier and a little harder. Relationships have benefits and drawbacks but in the overall picture the happy times outweigh the sad or else the relationship goes by the wayside.
And do not fret over the big city idea. Two things...you can also find romance with a person of the same gender in small towns and even if you go the big city route, you can at a later time move back to the smaller town with the person you love.
