Becky Holmes, 42, from Stratford-upon-Avon, claims to have received 50 explicit photos from men on Twitter since she joined at the end of August. She was contacted randomly by the man on Thursday evening.
Becky said: "I don't understand what it is about men where they feel they've got to display everything
"I'm not entirely sure where it comes from. As your following gets bigger and people re-tweet things, I suppose you're exposed to more perverts.
"I suppose I would consider myself to be a woman of the world, I'm not easily shocked.
"So for me it was a case of opening it and laughing thinking 'what on earth is that'? The people who send these photos don't discriminate in terms of who it's going to, you could be 13 or you could be 80.
"I've had women in their 80s contact me and say they've had these pictures."
He sent her a picture of his penis, swiftly followed by crude comments on her "bl*wjob" lips and describing what he'd like to do to her. Becky decided to publicly call the man out by sharing the lewd message in which she feigned concern about his health.
The man began debating whether his mole was OK and said he had it checked by a doctor, but prankster Becky warned him the end of his manhood may "turn black and wither". She even sent him a fake prescription complete with the NHS logo, ordering him not to send unsolicited explicit content to women again, wished him a Merry Christmas and reported him to Twitter.
Becky said: "I think it's for the shock factor. There are those I think who just get off on taking the picture in the first place, there are those who get off on sending it out randomly then there are people who like the replies.
"There are strangely some who will send these pictures and then try and get to know you as a person, and to me that's even more peculiar. It's the wrong way round.
After a three-day exchange, Becky drew a 'prescription' demanding he stop sending explicit pictures and messages to women.
Becky said: "Some people will be frightened if they're vulnerable, it's an invasion of privacy.
"I could just block and report to Twitter and that would be the end of it.
"I just feel if you approach it in the right kind of way then humour is sometimes a good way to get people talking.
The following day, on day four of the exchange, Becky 'broke cover' revealing she wasn't a doctor then rammed home the message that such behaviour is unacceptable.
The final message Becky sent read: "This is the situation... Every single day women are subjected to perverts like you - men who send them photographs of their genitals and crude descriptions of what they want to do to them.
"Women do not want these images. Ever.
"Some will ignore them, some will laugh at them, some will be upset by them. And then there are women like me.
"I am the worst kind for people like you, because I am the sort that will share your images across Twitter and have thousands of people laughing at you, which is exactly what I have done.
"I don't know whether you possess the intelligence required to feel any level of shame, but I hope you do, and I hope it stops you from ever sending a photograph of your tiny, shrivelled, insignificant penis to any other woman, ever again. Oh, and Merry Christmas."
Twitter rules and policies state that the site prohibits unwanted sexual advances.
