Is this common?

Okay, so being a part of the LGBQTI Community runs big in my family. It seems to be hereditary. I am a bi-female. My mother is bi. One of my mother's first cousins was a flamboyant gay. Another of my mother's first cousins is a cross-dressing male. One of my mother's 2nd cousins is a lesbian. One of my 3rd cousins on my mother's side of the family is a butch lesbian. And one of my 2nd cousins on my father's side of my family is gay. Who else can honestly say they have this many members of their family in such close proximity be a part of the community? Or can even say that it is hereditary in their family?
