IMO, these days we're living in are totally shocking. Lots of folks are like you (and me) don't appreciate references to the sexual parts of the body or sexual acts.
I was shocked to see a photo on my granddaughter's FB page. It was a photo from a bridal shower for her BFF. The cake was built to be a male penis. Ugh. And I heard that this is quite common at bridal showers.
So there's the new generation for ya. I shudder to think what their daughters will view as 'normal'.
