Male tortie and calico cats are extremely rare. Here's a little feline genetics lesson: The reason is that black and orange hair can only occur together in the hair coat if that cat has two X chromosomes. Calico cats (white cats with patches of black and orange) and tortoiseshell cats (black and orange swirled together), therefore, have to have two X chromosomes, and two X's means that you're a girl.
In order to be a boy, you need a Y chromosome. Boys are XY; girls are XX. Very rarely, a mutation occurs that leads to a calico or tortie male. Genetically, these cats are XXY. The two X's allows for the color; the Y allows for the maleness.
The incidence is reported to be 1 in 3,000.
In other words, out of every 3,000 cats with black and orange together in the hair coat, on average, 2,999 will be girls, and only one will be a boy. The XXY mutation leads to sterility. They can't reproduce. Your orange tabby girl is not sterile. Get her spayed.
Fun Fact:
Orange female cats are a little uncommon; only about 1 in 5 orange tabbies are female.

Are tortoiseshell cats female or male?
A tortoiseshell cat is a coat color where the cat is a molted brown cat with black, reddish, or orange patches. They can also have white paws. Tortoiseshell cats have unique genetics. The vast majority of tortoiseshell cats are female, because two X chromosomes are required to produce black, gold and orange coloring. Male cats only have one X and one Y chromosome, so technically it's genetically almost impossible for a male to inherit the tortoiseshell coloring. A male tortoiseshell has an extra X chromosome, making it an XXY. According to a study by the College of Veterinary Medicine at the University of Missouri, only 1 in 3000 tortoiseshell cats is male.
