Ok, for those who are just learning all this (where have you been?!) BGLT stands for Bi, Gay, Lesbain and Transgender. Whoa, what are these you may just be asking (hey, i was that ignorant once too, don't feel bad). No problem, i'll explain.
Bisexual basically means you have a sexual attraction to both men and women (what could be better?)
Gay basically means your a guy or man and your sexually attracted to other guys or men.
Basically, your a girl or woman sexually attracted to other girls or women.
A transexual is a person who feels that they were born in the wrong body and are actually of the opposite sex.
