No, you don't, but your G-Spot is a part of the same tissue that makes up the male prostate.

Every part of the male anatomy, women have, and every part of the female anatomy (except the womb - that I know of) men have. 

Penis = clitoris, and vaginal ceiling
Prostate = G-Spot (sorry forgot the clinical name)
Testicles = Ovaries
Scrotum = Labia

Female
Vagina, Uterus, & Cervix - undeveloped in the male.  They eventually degenerate.
Breasts - if a male takes female hormones, especially the younger he is, he'll develop fully functioning breasts.

Some women do find it easier to achieve orgasm if stimulated anally, however that also includes manual clitoral stimulation.

The prostate orgasm is completely different from the direct stimulation of the penis.  Similar to the difference between a G-Spot orgasm and a clitoral orgasm.

That's exactly why I switched dentist.

Oh god, if my dentis started giving me prostrate exams too I would never go to him again either.

I like how there is a man telling a woman about her private parts in this thread... Oh VGC... You never fail me.

Real or not I laughed so hard at this.

It happens in school too, if your teacher is male. Don't worry, when you eventually get to 7th grade you'll learn all of this, Pie. =)

:P

I'd take a less attractive female human doctor over a not so attractive alien doctor.  I hear those alien doctors like doing anal probes though, so they're probably good proctologists.  :/  So maybe get a prostate exam from a not so attractive alien doctor.  I don't know.

What makes you a male/female is the difference between X & Y.  Whether or not your body produces estrogen or testosterone at the right time during embroyitic development.  Up to a certain point both males and females look exactly the same.  Once sexual development starts, the gonads either decend to create testies, or travel up inside the abdomen to become ovaries.  In females the tip of the penis forms the clitirous and the shaft of the penis (penile tissue) forms the ceiling of the vagina (technically it's between the urethra and vagina), and in males the penis develops encasing the urethra.  In females, the area of skin that the testies decend into making the scrotum in males, splits forming the labia of the vagina in females.  In females the prostate forms a layer of squishy tissue between the ceiling of the vagina and urethra, in males this devlopes into a ball-like gland between the rectum and the penis, and surrounding the urethra.  

The major difference between males and females in regards to sexual organs is the uterus, cervix, and vagina.  There are a series of glands that merge to form the uterus, cervix, and vagina in females, where as in males they shrivel up, die, and become consumed by the body.

Unless sex ed has improved significantly in the US and around the world to include modern information, I'm guessing nobody learns much of this unless they actually look it up or take a human anatomy course in college. 

The kid is 13 years old lol...

Got a boner just reading the op.
