Masturbation Act of 1934
The Masturbation Act of 1934 prohibited public masturbation on Sundays until after nightfall. A consequence of the law was the creation of private masturbation clubs that allowed patrons to masturbate in front of others while not technically in a public place. Ultimately the law was overturned by the U.S. Supreme Court in 1935 - Johnson vs. Iowa.
I just shot my wad on the park bench. It’s a good thing the Masturbation Act of 1934 is no longer the law.
