Short answer: the labia majora
Long answer: In males, the scrotum and a portion of the penis (crus of the penis) develop from the outer genital folds. In females, the outer genital folds ultimately form the labia majora and crus of the clitoris.
The female structure that is homologous to the testes are the ovaries in females. Both function in the production of gametes.
in the female the BULBS OF THE VESTIBULE is homologous to the bulbospongiosus muscle, and corpus spongiosum
The female structure that corresponds to the male penis is the clitoris. The clitoris is a sensitive organ located at the top of the vulva and is a key erogenous zone in females, analogous to the sensitivity of the penis in males. Both the clitoris and the penis contain erectile tissue and are important for sexual arousal and pleasure.
the ovaries
The clitoris is the erectile tissue in the female. It is analogous to male penis. It gets erect during sexual excitement.
The scrotum. Not the testicles, just the sack that the family jewels hang in.

clitoris
The human appendix (a small sac near the junction of the small and large intestine) is homologous to a structure called the "caecum", a large, blind chamber in which leaves and grasses are digested in many other mammals.http://scienceline.ucsb.edu/getkey.php?key=3246
I learned about homologous and heterozygous structures in Biology.
A structure with similar shape but a different use
Two samples are said to homologous, in this context, when they are both very similar in structure and shape and more than likely function.
