Yes it should and the same should apply to woman who send body parts pictures to men unsolicited too.
There's always one.

Brother's ex-mate used to be prolific online dating (when in a relationship with SIL friend hence why brother dropped him), he always sent dick pics and said for every 2 women getting turned off he would get one sending back her own pics.
I don't believe this for a minute, and reckon your brother's 'ex-mate' is full of shit. Unless he was on a site where people were signed up to meet for SEX, then no WAY did 1 in 3 women send a pic of her fanny. Utter crap.
And yes, I absolutely WOULD report any man I knew doing this. Even a son, uncle, cousin. IDGAF. Being female myself, like the vast majority of women, I have had to put up with a LOT of sexual harassment (and even a couple of sexual assaults,) in the past.
And now seeing young female family members, and young female friends and acquaintances, having to tolerate the same SHIT; you can bet your fucking life I would report it to the police. I would frog-march the fucker to the police station myself.

Yeah but why only dick pics? I think this should cover ANY unsolicited nude photos sent from a male or a female. If sending unsolicited dick pics is a crime then so should be unsolicited and unwanted photos of breasts/nudes etc.
I said there's always one, but hey! There's ANOTHER.
Stop with your 'Not All Men Are Like That' and 'Women Do It Too' bollocks. Women do NOT send pics of their vulva, arse, tits etc etc, to a man that has simply asked to meet someone to date. MEN DO send pics of their dick and bollocks when a woman is simply looking for someone to date.. Happens all the time.
Women don't do it. Unless (as I said,) they are on a 'looking for someone for sex' website. I would think there is something seriously wrong with any woman who sent a pic of her fanny to some random man who was just hoping for a date with a woman, and I would try and get help for her.
As for men, I simply cannot get my head round why they do it. Whenever I have asked men I know, they just shrug their shoulders.
And as a few posters have said, the male appendage looks like the last chicken in the shop. It is NOT pretty. Why they think a woman will like it or be turned on by it just baffles me. Must be the same men who think a woman gets turned on by having a cervical smear, or by inserting a tampon. Men who are a bit thick.
Idiots.
