Something I’m moderately sure of is that May is National, maybe International, Masturbation Month. All ny sources seem to agree on that. From the current version of Wikipedia:
The first National Masturbation Day was observed May 14, 1995, after sex-positive retailer Good Vibrations declared the day in honor of Surgeon General Joycelyn Elders, who was fired in 1994 by President Bill Clinton for suggesting masturbation be part of the sex education curriculum for students.
International Masturbation Day has since been expanded to include the entire month of May as International Masturbation Month

(Note both vaginal and phallic symbols.)
Already there’s a question: why May 14th, back in 1995? Then things get quickly complex: an earlier version of the Wikipedia article, which I posted about here in 2013, identified Masturbation Day as May 7th (a date apparently selected by Good Vibrations in 1999) in the US, May 28th in some other countries. (Other US sources say May 28th is Masturbation Day.) Meanwhile, the current Wikipedia article says with great assurance that Masturbation Day is July 21st. The Wikipedia sources are in no way authoritative: they just assert dates. Thanks to the earlier Wikipedia article, I have May 7th on my calendar as National Masturbation Day, but now I’m all at sea. The 7th, the 14th, the 28th, or July 21st? And why? Why, in fact, May for the Month?
