The different names we use
I'm coming to the end of a month's trip around some parts of Europe, staying mostly with nudist Couchsurfers hosts and Misterbnb hosts.
I've found it amusing the different colloquial terms we use for our testes. This presented itself when using a translator app, as they often translate word by word, rather than using the meaning of the sentence.
In Portugal, testes are and referred to as 'tomatoes. In Australia, they are 'nuts or balls'. I think in Spain they are 'eggs.
So a translation may say, 'I like your eggs.'
Are different terms used in other countries?
In German, you say, Schwanz (tail) for cock. Also, Hahn (rooster) for cock.
Like Spanish, German uses Eier (eggs) as the slang equivalent for balls.
Just for reference, the correct and proper English word for what we call a penis is, in fact, cock. It was later assigned to roosters who are, if you ever watched one for very long, just a cock with wings and feathers -- and, like all birds, they don't even actually have one.
