All the bones in males are heavier than females, including the pelvic bone. This is due the effect of male hormone called as testesterone.
The shape of the pelvic bones and the frontal bones differ.
The pelvic bone is wider and more flared in females to allow room for childbirth.
Males do have a pubic bone. The pubic bone is the front bone portion of the pelvis or pelvic crest in the lower abdomen. Holds your hip bones together.
In humans The males bone is taller and thinner, whereas the females is shorter and wider ,almost butterfly shaped.
Pelvis/Pubis
Weight: Male: Heavier Female: Lighter Size: Male: In males the skull size is larger than that in females. Females: Smaller compared to that in males. The bony mass or the thicknes of the bone: Males: Thicker Females: Thinner Forehead:Males: In males the forehead is slightly sloping or receding. Females: The forehead is vertical. Vault of the skull: Males: The vault of the skull is more rounded. Females: The vault is flattened than that in females. Contour of the face: Males: The overall length of the skul is longer and the chin is bigger and projects more forwards, the skull is rugged due to its muscular makeup, and the zygomatic bones are also more massive.

One of the foot bones connecting the pinky to the metatarsal is different in females size and shape wise thatn the males wide bones.... Actually, male bone appear to be thicker and females are more smoother. Females faces are rounder while males are more squared. Girls have wider hip bones while males have smaller ones and so on......
The penis is a soft tissue structure and is not part of the pelvic bone.
There are many subtle differences but it's usually fairly obvious. A very general rule of thumb is considering whether you could fit a baby through the pelvic inlet (the space a baby would have to pass through during childbirth)? If so then it's probably a woman, if not it's probably a man. If you're interested there are more subtle differences, for example: In males the obturator foramen (the hole where some major leg muscles go) is round and in females it's oval. In males the acetabulum (the "socket" in the "ball and socket" joint where the femur (thigh bone) will attach) is larger than in females. The pelvic inlet (gap through the pelvis if you were looking down on it) is heart shaped in males and oval in females. The pubic arch (can't think of a way to describe it effectively has a large subpubic angle in women than in men. In men it's roughly shaped like an upside down V whereas in females it's wider (an angle greater than 90 degrees). In males the bones are thicker, heavier and taller and in females the pelvic bones are lighter and less dense. There are other differences as well but in most cases these would be enough to make an assessment of gender.

That is the tail bone.
