Definitions define...sometimes.

No one wants to be defined in a couple of words. 
By their race, neighborhood, color, country of origin, or sexuality.  Just to name a few of the ways we manage to marginalize each other. 
So, while I want to give some basic definitions for you, I by no means think I have all the answers.  This is a guide and offered as information only.  It's pretty simplified, hopefully not OVER simplified. 
I hope you find this interesting, offers you insight and offers a chance to embrace our differences and learn more about each other!

Lets start with LGBTQ+

Lesbian - homosexual women.

Gay - usually referring to homosexual men, however, "gay" can be an umbrella term for homosexuality.
 
Bi Sexual - a person that can feel sexual and/or romantic attraction to either men or women.  This can sometimes overlap with "Pansexual" as well.

Trans Sexual, Trans Gender (sometimes "Transitioning"). 
"Transexual" usually refers to "what's between your legs".  Transexual people can be straight that sometimes or always present themselves to the world as opposite to what their sexual organs look like, or can be homosexual or bisexual. 
"Transgender" is more "what's between your ears".  Just because you were born with a certain anatomy, doesn't mean you "feel" like that sex.  Occasionally, people transition to the sex that they feel that they belong to, whether that makes them hetero or homo sexual.  

Queer (sometimes "Questioning").
"Queer" was often used as an insult to anyone that wasn't heterosexual.  This population also "took back" the term so that it is more of an umbrella term that embraces everyone, rather than insults or puts down. 
"Questioning" is just that- not sure. Maybe still figuring it all out.  But all in good time as as it's supposed to be. No rush. 

...and what does "+" mean? 

Until next time!
