'Erotica', if you prefer. I read a lot of it. The Internet has a wealth of it, really. But also, I read those stupid romance novels where the heroine is always falling out of her clothes on a rainswept mountain with some cowboy/pirate/ man who bought her family's business. I love those things. There is absolutely nothing more amusing than flipping through one of those things to see just how many different words can describe the male anatomy.
There is a MULTITUDE. For example...
Then there are special cases.
First, let's discuss 'Rampant Erection'. 'Rampant' itself means many things. *Courtesy of Merriam-Webster's Dictionary*
It could mean: rearing upon the hind legs with forelegs extended.
Or even: standing on one hind foot with one foreleg raised above the other and the head in profile.
Or perhaps: having one impost or abutment higher than the other.
And lastly: marked by a menacing wildness, extravagance, or absence of restraint.
Ah. So it's a menacing tool of pleasure, wielded by all men. Cute choice of adjective.
