Apparently, this is the author’s best work:
“It’s difficult to love a woman whose vagina is a gateway to the world of the dead . . .”
Book description:
Steve falls madly in love with Stacy, but it isn’t until they move in together that he hears voices coming from Stacy’s southern junction. When a skeletal creature makes it’s way through Stacy into their world, Stacy convinces Steve he must go exploring to find out where this mysterious passage leads. After his fist foray, Steve almost doesn’t make it back from the alternate world, but the next time Stacy sets him up for a full spelunking.
More info on The Haunted Vagina (2006) by Carlton Mellick III, writer of the lost classic Razor Wire Pubic Hair, here and here. There seems to be an underlying theme here…

OK, my brain just broke again for the SECOND time tonight.
I’m wondering whether “fist foray” is a typo, seeing as they have an apostrophied possessive “it’s” as well.
I really don’t know, this kind of kinkiness is just not my scene. I mean, spelunking?! I had to search my damn dictionary for that, and then went “Ooooohh…”. Definitely not a typo.
