>>211990901There's three degree of female lower nudity:
-bush
-pussy (vulva visible, but nothing explicitly gynecological)
-pink (inner labia spread open)
The first is easy to fake with a merkin, and frequently is. The second can be faked with prosthetics, but prosthetics less convincing and rarely if ever resorted to for women (unlike prosthetic penises, which are quite common for male actors).
