How do you identify yourself if you are gay and what are the things you usually do and things that you think and behaviors you usually do if you are gay? Same with being bisexual what are your behaviors and things that you usually do and think?
There is no right answer to your question. You're most likely thinking about the Hollywood Gay, involving tons of stereotypes. There is no way in which gay or bisexual individuals act differently than if they were straight, aside from also having an attraction to someone of the same sex. Aside from your question, you posted this under Gender Identity, while it should be tagged under Sexual Orientation. Gender Identity is someone that is unsure about their gender.
Who do you see yourself to live with? Not to have sex. Living, shopping, cuddling, arguing, getting older with? And by the way it is common and PERFECTLY ALL RIGHT to not know that at the age of 14. Give it time and explore your feelings.
