Another thread here reminded me of a story.
Years ago, my job was offering the employees a class in cardiopulmonary resuscitation (CPR), with “hands on” training. I wanted to take it, but was worried about the physical stuff, and expressed to a co-worker, “I’d be happy to take the class, but before I sign up I want some idea about which girls and women I‘m going to be doing mouth to mouth with”.
She laughed and said, “Breuk, they use dummies!”.
I replied, “I don’t care how smart they are - I just want to know what they look like!”
