Can"t Find Gay Gene

The song "I Was Born this Way,by Lady GAGA" pretty much sum up the way I feel about my sexuality. I as far as I can remember back I have always been attracted to girls as my sexual preference and admired boys. Now as far as where did my gay gene go or where is the marker I don't know. However, where is the straight gene or marker? Have science found that marker? I would suppose where the straight gene is found. That's where the gay gene will be found. May be our sexual taste is not something that is important enough to have a spot on the DNA ladder. Yes, we are born either male are female in our physical appearance, but our genital does not dictate what sexual partner we crave. There is something else that control whom we have sex with. So until science find the straight as well as the gay gene I believe we can all sing together "I Was Born this Way".
