Do you remember that I once wrote that Engels bragged in a letter To Marx about all the French teen prostitutes he fucked on his vacations in France?
I couldn't find the quote again but this video cites it.
A Grisette was a young, unmarried woman who often worked in "entertainment".

So Engels was probably a hepephile!
