Possible. I think she is a sex addict. I searched and find a few symptoms and Asperger's was mentioned
Here is a selection of the symptoms
People with Borderline Personality Disorder engage in unsafe sexual activities as a general pattern of self-injurious behavior.
Often those with severe identity confusion regarding their own sexual orientation engage in compulsive sexual behavior.
Victims of childhood sexual abuse often repeat pattern of abuse in a subconscious attempt to gain control over their childhood trauma. People in this category generally suffer from posttraumatic stress disorder.
Adolescents and young adults who are intellectually delayed can develop a pattern of compulsive sexual behavior, as a result of not having developed an accurate understanding of healthy sexuality. People with Asperger’s Syndrome may be at greater risk of exhibiting out-of-control sexual behaviors.
