Okay well, I realize it's been around forever but it just ain't my cuppa.
I've read "Thy Daughter's Nakedness" and I've read Portnoy's Complaint. I was spellbound as a horny teen with the wild exploits of Xaveria Hollander, and none of those fired my interest in it.
Different strokes for different folks, this was one stroke I wasn't ever going to be curious about.
