winney, I am so sorry this happened to you. I would feel violated too. Is there any news on what happened to your neighbor? Did she file a report. I really hope that she is okay.
Go you for being so proactive in making sure your neighborhood remains a safe place for all that live there. I applaud you.
Now on to the whole is this or isn't this a sex crime debate I decided to look up the defination of a sex crime and here is what I found (I posted the link below the defination):
Sex crimes are forms of human sexual behavior that are crimes. Someone who commits one is said to be a sex offender.
Some sex crimes are crimes of violence that involve sex. Others are violations of social taboos, such as indecent exposure.
There is much variation among cultures as to what is considered a crime or not, and in what ways or to what extent crimes are punished.
Acts regarded as crimes almost universally include the following non-consensual sex crimes:
Child sexual abuse or molestation
Child pornography (definition varies significantly)
Incest
Lust murder
Rape, sexual assault and other forms of sexual abuse
Sexual harassment is also viewed as a crime in Western cultures.
Liberal western cultures are far more tolerant of acts such as oral sex or transvestism that have traditionally been held to be crimes in some other cultures, but combine this with lesser tolerance for the remaining crimes.
Cultures with highly censorious sex laws regarding adult sex acts often have high levels of concealed sexual abuse, particularly of children.
Many consensual sexual actions or activities are only viewed as crimes in some jurisdictions, including:
Adultery
Anal sex
Sex among juveniles (usually as Statutory rape)
Homosexuality
Oral sex
Various Paraphilias/Fetishes such as
transvestic fetishism
BDSM
Pornography
Prostitution and/or pimping
Ownership of vibrators and other sex toys

So the way I'm reading it is that indecent exposure "might" be considered a sex crime but it might be more "social taboo".
Just thought I would post the information so that it would be a bit clearer on what is considered a sex crime and what isn't.
I personally considered it a sex crime because what he did was sexual in nature, but I would guess that it varies from state to state and police department to police department.
