I think we should have an entire topic labeled- "Things That Are Asked Way Too Much And Have No Correct Answer" Questions would include- Penis size Boob size Butt size Curvy? Skinny? And he infamous "he looked at me, does he like me?" Questions.
Sounds great. Two important considerations, though: What about breast size questions whcih get just as annoying? And make sure that posting a penis size question under any other topic is a violation and it will be removed immediately.
To be fair, as much as I am tired of seeing these questions, girls also put out lots of questions about their labia and their boobs. I think seeing stuff about genitals is unavoidable just as much as rate me questions. Everyone has insecurities, though some take it a bit too far.
I'm not sure it would help. A lot of them aren't really questions, they are the equivalent of broadcasting a dick pic. The people doing it aren't going to want to post in a place where it won't be seen by most people.
Many of the boob questions, 'I'm a 34ggg are my boobs too big?" are the same.
Yes, I do agree they are annoying BUT, They are IMPORTANT. They have to deal with guy's insecurities about their size and they really want to know. If you make that a topic, dont make only that the topic, add boob size, labia size, etc. that girls ask a ton too.
