Avery, a 25-year-old woman, experiences pain during vaginal intercourse. She avoids sexual encounters, fearing pain may occur. The muscles around her vagina tighten during vaginal intercourse and make penile-vaginal intercourse difficult. Which of the following is suffered by Avery in this scenario?

A) Peyronie's disease
B) female sexual interest/arousal disorder
C) ovarian hyperstimulation syndrome
D) genital-pelvic pain/penetration disorder

Avery is suffering from genital-pelvic pain/penetration disorder (GPPPD), which is characterized by difficulties with vaginal intercourse due to pain or discomfort. This disorder can also cause involuntary tightening of the pelvic floor muscles, which can make penetration even more difficult or even impossible. GPPPD is a type of sexual pain disorder that affects women and can have many different causes, such as psychological factors, past traumatic experiences, or physical conditions such as vaginal infections or endometriosis. Avery should seek medical attention and possibly work with a therapist to help manage her symptoms and improve her sexual experiences.
