How can I tell the sex of my rabbit?

Like what should I look for down there?How can I tell the sex of my rabbit?
To determine the sex of the rabbit, use your forefinger and middle finger to press down the vent area just in front of the anus. In both the doe and buck, the area will protrude. The doe will display a slit or central line running up and down. Each side of the slit will be banded in pink. The buck, on the other hand, will display, if less than 5 weeks old, a blunt white tube without a central line. It will not have pink traversing either side of a center line. Older bucks will present a pink tube with a pointed end that resembles a bullet. With younger rabbits, you must look very closely to see the difference.
