Im not sure if i might be bi/lesbo

how would you know if you were a lesbo or bi
besides the obvisous you like girls

If you aren't sure then don't pressure yourself, as you get older and get more experience you'll learn more about your sexuality.

Experiment, but I wouldn't try that till your over the age of 18. You don't want to make a stupid mistake when you're young and regret it later,

straight = your sexually attracted to the opposite sex only
gay/lesbian = your sexually attracted to people of the same gender as you
bisexual = your both equally sexually attracted to both males and females
bi-curiose= your sexually attracted to the opposite sex but are open to experimentation with people of the same sex
