I've read it years ago, don't remember that scene but it sounds about right. There is one scene where he kinda spies on these two women making love and he spends ages describing the smell of their cunts and how it's unmistakable and how he's such a connoisseur of vaginal smells and so on and it goes on for ages before he realises that the window is closed and what he's actually smelling is an open dustbin outside the window.Apparently a man wanks on a woman's grave in Sabbath's Theater. It sounds like what I imagine a parody of Roth would be.
Isn't Portnoy's complaint just one long sentence? If I remember rightly he just kinda rants to his psychiatrist about wanking for about 100 pages... it's a small book.
Yes, it is basically a monologue about wanking, wanting to wank, feeling bad about wanking and feeling bad about wanting to wank. It is also an exploration of Jewish identity and wanking.
No wonder Corpsey loves it so much.
