JOB APPLICATION (AND SEXUALITY)

Today I'm in my 2nd day Job Application. I approved my interview, but now (since I've had many job experiences) they will ask me, in between, to draw A PERSON, then A PERSON FROM THE OPPOSITE SEX. For me, I guess also for many of you too, WOMEN are NOT OUR "opposite sex" since we are not BEHIND THEM for a sexual intercourse, or to "make a family" with one of them. So, I mentally graphiqued my sexual opposite and, in the first case, my muscular Alter Ego. What if I do this... will they reject my job rights only for being homosexual? Do I need to sexually intercourse with the clients to sell stuff??? Every comment will be welcome
