Report with the picture attached. And then don't worry about it. Unfortunately there are crazy people everywhere. A little creepy as well.

Take comfort you found this out now,rather than in a relationship.....

Why do men do this? Does he think that by actually seeing “the goods” it will persuade you to change your mind, or is it just to shock and annoy you? The latter I presume. It’s juvenile behaviour although I am assuming he’s much older and well beyond the adolescent stage. Block him, report him, ignore him...and then forget about him, that’s my advice.

Justifiably upset. Unsolicited dick pics are a threat. Report him.

I'm sorry you have had to endure this BS, especially from a person on a website where you ought to be able to expect better from people.

If he he sent you his pic on this site, do a screen shot and send to Administration with your explanation. I know that sounds vile, but sometimes a so called "paper trail" is necessary to eliminate such activities.

He's a jerk. Flush the toilet and imagine him swirling down the drain.

This is his problem, not yours. Let it go.
