Its hard to be gay when you are young and not out yet. - Things would be easier when you are openly gay but then again it could make things harder at school. Think it would be easier to find good friends that are girls and other gays when you are open about your sexuality. To be honest theres small chance that hes gay as well cause only 5% of people are.
However there are plenty of gay meeting places - clubs, bars, forums etc. So you are not alone. Eventually you will get hang of it.
Doubt kills more dreams than failure ever will
